Ordering clothes online comes down to one worry: will it fit? This guide explains the difference between oversized and regular-fit t-shirts, how to measure yourself in two minutes, and which size to pick.
Oversized vs regular fit: the difference
- Regular fit follows your shape: the shoulder seam sits on your shoulder, the sleeves are close to the arm and the hem sits around the hip.
- Oversized fit is cut bigger on purpose: the shoulder seam drops below your shoulder, the sleeves are wider and longer, and the body hangs loose.
Because the extra room is built into the pattern, you take your usual size in an oversized tee. Sizing up a regular tee doesn't give the same look — the shoulders become too wide before the body feels relaxed.
How to measure yourself
You need a tape measure (or a string and a ruler) and a tee that fits you well.
- Chest / bust: measure around the fullest part, under the arms, keeping the tape level.
- Shoulder: measure from the tip of one shoulder to the tip of the other, across the back.
- Length: measure from the highest point of the shoulder down to where you want the hem to sit.
Keep your body relaxed and the tape snug, not tight. Measurements can vary by about half an inch.
No tape on you? Lay your best-fitting t-shirt flat, measure straight across the chest from armpit to armpit and double it. Compare that, and the length, with the chart.

What about oversized sizes?
Our oversized tees are labelled S-38, M-40, L-42, XL-44 and XXL-46. We don't publish a separate oversized chart yet: the regular-fit chart above is your guide, and the oversized cut adds room through the chest and body on top of it. So:
- Want the classic slouchy look? Take your usual size.
- Want it closer to the body? Go one size down.
- Between two sizes? Take the bigger one for an oversized tee, the smaller one for a regular tee.
If you want the exact measurements of a particular garment, message us on WhatsApp and we'll measure it for you.
Does cotton shrink?
Most of our tees are 100% bio-washed cotton, which is pre-treated and shrinks very little. Washing in cold water and drying in the shade keeps the fit — our care guide has the details.
If it doesn't fit
You can request an exchange or return within 7 days of delivery. Keep the tee unworn and unwashed with its tags, and see our returns policy for the steps.
