Fit Is Everything (And Nothing Like You Think)
You can own the most expensive wardrobe on earth. Premium fabrics, flawless construction, perfect colors. But if the fit is wrong, none of it matters.
Here's the uncomfortable truth: most people wear the wrong size. Not because they don't know their measurements, but because they're following outdated "rules" about how men should dress vs how women should dress, what "flatters" certain body types, or what size they "should" be.
This guide throws all of that out. We're going to talk about fit as a function of comfort, proportion, and intention—not gender, not body shame, not arbitrary fashion rules. Just physics, ergonomics, and what actually works on human bodies.
The Universal Principles of Good Fit
Before we talk about body types, let's establish the non-negotiables that apply to everyone:
1. Shoulders Should Align
The shoulder seam of any structured garment (jackets, coats, tailored shirts) should sit right where your shoulder naturally ends—that bony point where your arm connects. Not drooping down your arm. Not pulling tight across your back. Right. There.
This is the hardest fit point to tailor, so get this right first. Everything else can be adjusted.
2. Chest and Torso Need Breathing Room
You should be able to comfortably move, reach, and breathe without fabric pulling tight. For button-ups: if you see horizontal pull lines across the chest when buttoned, size up. For t-shirts and sweaters: you want fabric to skim your body, not vacuum-seal it or tent over it.
The "pinch test": pinch the fabric at your side. You should be able to grab 2-3 inches of fabric. Less than that? Too tight. More than 5 inches? Too loose.
3. Length Determines Proportion
T-shirts and sweaters should end somewhere between mid-fly and mid-thigh, depending on the style. Too short reads as undersized or cropped (fine if intentional). Too long reads as oversized or sloppy (also fine if intentional).
There's no "correct" length—only intentional length. Decide what silhouette you're going for, then commit to it.
4. Sleeves Are About Function
Short sleeves should hit mid-bicep to just above the elbow. Long sleeves should end at your wrist bone when arms are relaxed. When you raise your arms, sleeves can ride up to mid-forearm—that's normal.
Sleeves that are too short look juvenile. Sleeves that are too long look borrowed. Get this right and everything else falls into place.
5. Pants Are About Movement
Waist: Should sit comfortably where you naturally want them to sit (everyone's different). You shouldn't need a belt to keep them up, but you should be able to fit two fingers inside the waistband when buttoned.
Rise (crotch to waist): Low-rise, mid-rise, high-rise—all valid. the is that fabric shouldn't pull or bunch when you sit, walk, or bend.
Leg opening: Personal preference. Skinny, slim, straight, wide—all work. The test: can you comfortably get your shoes on and off? Can you crouch down? That's a good fit.
Length: Full break (fabric pools at shoes), half break (slight fold), no break (hits top of shoe), cropped (shows ankle). All intentional. All valid. Avoid accidental in-between lengths.
Body Types: A Framework, Not a Prison
Body type guides are useful as reference points—not as rules. You're not "stuck" dressing a certain way because of your proportions. But understanding your proportions helps you make intentional choices instead of random ones.
Athletic/Broad Shoulders
Proportions: Shoulders wider than hips, defined chest/back, narrower waist.
What works: You can wear most things well. The challenge is avoiding overly tapered fits that create a "superhero" silhouette unless that's your goal. Relaxed and straight fits balance your proportions naturally. Structured shoulders in jackets emphasize width (great if you want presence). Dropped shoulders in tees/hoodies soften the look.
What to watch: Button-ups can pull tight across chest while being loose at waist—get the chest right and tailor the waist if needed. Avoid sleeves that are too tight on biceps/forearms.
Slim/Linear Build
Proportions: Similar width from shoulders to hips, less defined waist, often taller or longer-limbed.
What works: Layering is your superpower. You can add visual weight and dimension through texture and volume without looking bulky. Oversized fits work exceptionally well—they add presence without overwhelming your frame. Cropped layers add horizontal lines that break up vertical length.
What to watch: Avoid extremely slim fits that emphasize thinness. Looser, more relaxed silhouettes add substance. Don't be afraid to size up and embrace volume.
Balanced/Proportionate Build
Proportions: Shoulders and hips roughly equal width, defined or undefined waist, medium frame.
What works: Literally everything. You're the "fit model" that most brands design for. Use this freedom to experiment with different silhouettes. Try oversized, try tailored, try relaxed—see what feels right.
What to watch: Don't default to "standard" fits just because they work. Push yourself to try different proportions and see what resonates with your style.
Curvy/Rounded Build
Proportions: Defined curves, fuller chest/hips/thighs, rounded rather than angular lines.
What works: Structured fabrics that hold their shape (heavyweight tees, sturdy hoodies, quality denim) skim your body without clinging. Relaxed fits give you room to move and breathe. Mid-to-high rise bottoms prevent gapping and sliding. Avoid ultra-thin fabrics that cling or show every line—thicker, structured materials drape better.
What to watch: Ignore "flattering" advice that tells you to hide your body. Wear what feels good. If you want slim fits, wear slim fits. If you want oversized, go oversized. The only rule is fit and comfort.
Petite/Shorter Build
Proportions: Shorter overall height (usually under 5'6"/168cm), proportionally shorter limbs and torso.
What works: Cropped lengths (jackets, hoodies, tees) maintain proportion without overwhelming your frame. Higher rise pants create the illusion of longer legs. Monochrome or tonal dressing creates vertical lines. Avoid excessive fabric pooling—hem pants and sleeves if needed.
What to watch: Oversized can work beautifully if done intentionally (shorter jackets, cropped oversized tees). But avoid standard-length oversized pieces that drown your proportions. Tailoring is your best friend.
Tall/Longer Build
Proportions: Taller overall height (usually over 6'0"/183cm), proportionally longer limbs and torso.
What works: Longer inseams, taller torso cuts. Brands that offer "tall" sizing are your best bet. Layering adds horizontal lines that break up height. Looser, boxier fits add width and balance out length. Cropped pants (showing ankle) work exceptionally well on tall frames.
What to watch: Standard sizing often results in high-water pants and half-sleeve shirts. Seek out brands with tall options or expect to hunt for longer inseams. Don't settle for ill-fitting length.
The Relaxed/Oversized Fit Philosophy
1ABEL is built on relaxed, oversized fits with dropped shoulders. Here's why that works for almost everyone:
Dropped Shoulders: The shoulder seam sits 1-3 inches past your natural shoulder line. This creates a relaxed, effortless silhouette that works across body types. It removes the stress of perfect shoulder fit.
Relaxed Torso: Extra room in chest and waist allows natural movement without restriction. Fabric skims rather than clings. This is comfortable, breathable, and creates clean lines.
Slightly Extended Length: Tops hit lower (mid-thigh to upper thigh) for coverage and proportion. Bottoms have fuller legs with slight taper to avoid looking sloppy.
This fit style is forgiving, comfortable, and modern. It works whether you're athletic, slim, curvy, or balanced. It's not about hiding—it's about ease.
How to Find Your Fit
Step 1: Know Your Measurements
Grab a fabric measuring tape and record these numbers:
- Chest: Measure around the fullest part of your chest/bust, tape parallel to floor
- Waist: Measure around your natural waist (smallest part of torso)
- Hips: Measure around the fullest part of your hips/butt
- Inseam: Measure from crotch to floor (inside leg seam)
- Sleeve: Measure from center back neck, over shoulder, down to wrist bone
- Shoulder: Measure from one shoulder point to the other across your back
Write these down. Compare them to brand size charts. Don't assume you're always a "medium" or size "32"—sizing varies wildly between brands.
Step 2: Try It On and Move
Stand in front of a mirror wearing the garment. Now:
- Raise your arms overhead. Does fabric pull tight? Ride up excessively?
- Sit down. Does the waist dig in? Do thighs feel restricted?
- Reach forward. Do shoulders pull back uncomfortably?
- Walk around. Does anything bunch, slide, or feel awkward?
If you're restricted in any of these movements, the fit is wrong. Clothes should move with you, not against you.
Step 3: Check the Visuals
Look at your silhouette:
- Are there horizontal pull lines? (Too tight)
- Is fabric billowing or excess pooling? (Too loose or wrong cut)
- Does the garment hang evenly? (Check left vs right side)
- Do proportions look intentional? (Not accidental crop, not accidental oversized)
Step 4: Ask Better Questions
Instead of "Does this flatter me?" ask:
- Does this fit my lifestyle? (Comfort, function, movement)
- Does this match my aesthetic? (Oversized, tailored, relaxed)
- Do I feel like myself in this? (Confidence, ease, authenticity)
"Flattering" is subjective and often rooted in outdated beauty standards. "Functional and authentic" is objective and personal.
The 1ABEL Approach to Fit
At 1ABEL, we design for real bodies and real lives. That means:
- Relaxed, oversized fits with dropped shoulders for comfort across all body types
- Unisex sizing based on measurements, not gender
- Premium heavyweight fabrics (220-600 GSM) that hold their shape and drape well
- Extended size ranges (XS-XL for most pieces, 28-42 waist for bottoms)
- Detailed size charts with flat-lay measurements so you know exactly what you're getting
Try your usual size first, but if you're between sizes or prefer different fits:
- Size up for extra oversized, longer length, more room
- Size down for a less oversized look (but it'll still be relaxed, not slim)
Every body is different. There's no "correct" size—only the size that works for you.
Final Fit Principles
- Fit is function. If it doesn't move with you, it doesn't fit.
- Comfort is non-negotiable. Clothes should feel good, not restrictive or awkward.
- Proportions are intentional. Decide what silhouette you want, then commit.
- Your body isn't the problem. Poor fit is a manufacturing issue, not a you issue.
- Size is just a number. Buy what fits, not what you think you "should" be.
- Tailoring is always an option. A $30 tailor can transform a $200 piece.
- Try before you settle. Order multiple sizes if you're unsure. Return what doesn't work.
- Trust your gut. If something feels off, it is. Find something better.
Good fit isn't about following rules. It's about understanding your body, knowing what you want, and finding pieces that deliver both comfort and confidence. Everything else is noise.
