Sizes here run S to XXL, and headwear is one size. The letter on the label is not the useful part — the fit it was cut as is. This page tells you how to measure, what the three fits do, and which one to pick.
Per-garment measurements are not published yet. They are taken off the production samples with a tape and go on each product page; until they are there, we are not going to print a chart we have not measured. Use the method below against a garment you already own, or ask us and we will measure the sample for the piece you are looking at.
The one thing that works: measure a garment you already own
Body measurements tell you about your body. Garment measurements tell you about the clothes. Streetwear is cut deliberately away from the body, so the second is what decides whether you like it.
Find the piece in your wardrobe that fits the way you want this one to fit. Lay it flat on a table, smooth it out, and measure it with a tape. Write the numbers down. Those numbers are your target, and every size question after this becomes arithmetic instead of guesswork.
How to measure, garment by garment
Tees, hoodies and crewnecks
| Measurement | How to take it | What it decides |
|---|---|---|
| Chest (pit to pit) | Flat, from one underarm seam straight across to the other. Do not double it — this is the half-chest, and it is the number everyone compares. | Everything. Get this within a centimetre or two of your target and the rest usually follows. |
| Body length | From the highest point of the shoulder, beside the collar, straight down to the hem. | Whether it sits on the waistband or below it. Oversized cuts add length as well as width, which is what stops them looking like a shirt two sizes too big. |
| Shoulder | Seam to seam across the back. | On a regular fit, where the sleeve seam lands. On an oversized cut the seam is meant to drop past the shoulder, so a wide number here is the design and not an error. |
| Sleeve | From the shoulder seam to the cuff, along the outside of the arm. | Cuff position. Long arms should read this before the chest. |
Cargos and joggers
| Measurement | How to take it | What it decides |
|---|---|---|
| Waist | Flat across the top of the waistband, edge to edge, relaxed — not stretched. | The size. On an elasticated or drawcord waist, take the relaxed number and check the stretched one too; the gap between them is your margin. |
| Inseam | From the crotch seam straight down the inside leg to the hem. | Where the hem breaks. Cargos are cut to stack on the shoe; if you do not want that, this is the number to check first. |
| Rise | From the crotch seam up to the top of the waistband at the front. | Where the waistband sits. A high rise on a relaxed leg reads very differently from a low one, and it is what most "these look wrong on me" returns turn out to be. |
| Leg opening | Flat across the hem, edge to edge. | How wide the leg finishes. On a jogger this is the cuff and it will be much narrower than the thigh. |
Shorts
Same as above minus the inseam question: measure the waist flat and relaxed, then take the outseam — from the top of the waistband straight down the outside to the hem — because that is what tells you where the hem lands on your leg. Inseam on a short is a small number that varies between makers and tells you very little.
Cap and beanie
Both are one size. Run a tape around your head just above the ears and across the middle of the forehead, snug but not tight. That number is your head circumference, and it is the only one that matters for headwear. If you are outside the usual adult range at either end, ask before ordering rather than after — a one-size piece that does not fit is a return we would both rather avoid.
The three fits, and what they actually mean
Every product page carries a Fit tag. It is not decoration: it is the difference between two garments with the same letter on the label.
| Fit | What it is | How to size it |
|---|---|---|
| Regular | Cut close to a standard body block. Straight through the body, sleeve seam on the shoulder. | Take your usual size. |
| Relaxed | Wider through the chest and body than regular, with the shoulder still roughly where a shoulder is. Room to move without volume. | Take your usual size. Size down only if you want it to read as regular. |
| Oversized | Cut wide and long on purpose, with the sleeve seam dropped well past the shoulder. The volume is the design. | Take your usual size and you get the intended look. Size down for something closer to relaxed. Do not size up unless you have measured a garment and know what you are asking for. |
Layering
A hoodie worn over a heavyweight tee needs the room to go over it. If you intend to layer, measure the tee you will wear underneath, flat, and use its chest measurement as the floor for the hoodie rather than your own. Two garments cut to the same chest do not layer; they bunch.
Between two sizes
Take the larger one on tops and the smaller on bottoms. Tops are worn away from the body here and an extra centimetre across the chest reads as the cut; a waistband that is a centimetre loose reads as the wrong size all day. If you would rather not guess, tell us the two sizes and the flat chest or waist measurement of the garment you are comparing against, and we will answer with a number rather than an opinion.
Washing, and whether it will shrink
Follow the care label sewn into the garment — it is the manufacturer's instruction and it wins over anything written on a web page, including this one. As a general matter, cotton jersey and fleece shrink most in heat, so cold wash and air dry is the setting that keeps a garment the size you bought. A piece that shrank in a hot dryer has not developed a fault.
If it does not fit
Separately from our own returns policy, loi 31-08 gives you seven days from delivery to withdraw from a distance sale, for any reason or none. Both are set out in full in the returns policy. Our own window and the exchange route are set out in the returns policy, including how a refund reaches you when you paid the courier in cash. Unworn, tags on, and tell us before you send anything back so it arrives with a reference on it.
