Size Matters: A Comprehensive Guide to Finding the Right Fit

Fit is everything. A perfectly sized piece looks intentional; an off-size one just looks off. The problem is that sizing across brands — and even across product lines within the same brand — can vary a lot. This guide will help you get it right every time.

Why Sizing Is So Confusing

Clothing sizes were never standardized globally. A Medium in one brand is a Large in another. Add in the difference between fitted, regular, and oversized cuts, and it's easy to see why so many people guess — and get it wrong.

The only real solution: measure yourself, then compare to the size chart.

Step 1: Get Your Measurements

You'll need a flexible measuring tape (the kind used in tailoring, not a rigid metal one). If you don't have one, a piece of string and a ruler works too.

Wrap the tape horizontally around the fullest part of your chest, under your arms. Keep it level and snug but not tight. Note the measurement in cm.

Measure around your natural waist — the narrowest part of your torso, usually about 2–3 cm above your belly button.

Measure around the fullest part of your hips and seat, usually about 20 cm below your natural waist.

Measure from the top of your shoulder straight down to where you want the hem to fall.

Step 2: Compare to Our Size Chart

| Size | Chest (cm) | Waist (cm) | Hips (cm) | |------|-----------|------------|----------| | XS | 82–87 | 66–71 | 88–93 | | S | 88–93 | 72–77 | 94–99 | | M | 94–99 | 78–83 | 100–105 | | L | 100–106 | 84–90 | 106–112 | | XL | 107–113 | 91–97 | 113–119 | | XXL | 114–120 | 98–104 | 120–126 |

Step 3: Consider the Cut

Our products come in different fits. Here's what they mean for sizing:

True to size. If your measurements fall between two sizes, go with the smaller one.

Intentionally large. Size down one if you prefer a relaxed-but-controlled look. Stay true to size if you want the full effect.

Cut closer to the body. If you're between sizes, go up one.

Common Fit Issues & How to Fix Them

The shoulders don't sit right. This is the most important point of fit. If the shoulder seam doesn't align with your actual shoulder, the whole garment will look off. Prioritize getting this right — everything else can be adjusted.

The torso is too long. Try a shorter cut or look for "cropped" versions in our catalog.

The sleeves hit in an odd place. For t-shirts, sleeves should end mid-bicep. For long-sleeves, at or just below the wrist bone.

It fits the chest but not the waist. Welcome to the world of tailoring. A good tailor can take in a garment's sides for $10–20, turning a good piece into a perfect one.
