How to Choose the Right Size for an Oversized T-Shirt (Men & Women)

An oversized fit isn’t the same as “sized up.” It’s a different pattern altogether — drop-shoulder construction, extra chest room, added body length — and buying it like a regular tee is the most common reason people end up either swimming in fabric or wearing something that just looks like a baggy mistake. Here’s how to actually get it right.

What makes an oversized fit different from a regular fit?

Three things: the shoulder seam, the chest, and the length.

On a regular-fit tee, the shoulder seam sits on your shoulder bone. On an oversized tee, it drops down your arm — usually 2–4 cm past the natural shoulder point. That drop is what creates the relaxed silhouette; it’s not just “a bigger size of the same shirt.”

The chest also carries more room than a regular fit at the same size label, and the body runs longer at the hem — enough to sit past the waistband without you having to size up just for length. Buy an oversized tee expecting a regular-fit chest and you’ll end up with a shirt that reads accidental, not intentional.

Should I size up or size down for an oversized tee?

Neither, usually. Oversized fits are already cut with the extra room built in — that’s the point of the pattern. If you take your normal size in a well-made oversized tee, you should get the drop-shoulder look without needing to size up.

The exception: if you’re between two sizes on a brand’s chart, or you specifically want a more exaggerated, boxier look, sizing up by one is reasonable. Sizing up twice usually pushes the shoulder seam too far down the arm and the proportions stop working.

How do I measure myself for an oversized t-shirt at home?

You need three numbers, and a soft measuring tape is enough:

1. Chest — measure around the fullest part of your chest, tape level all the way around, not pulled tight.
2. Shoulder-to-shoulder — with a shirt you already own laid flat, measure seam to seam across the back.
3. Length — from the highest point of the shoulder straight down to where you want the hem to sit (oversized hems typically sit lower on the hip than a regular tee).

Compare these three numbers against the size chart rather than going off your usual S/M/L label — oversized sizing runs differently brand to brand, and this is the step most returns skip.

If you want an even more precise fit, the full LURI chart below also covers sleeve length, sleeve opening, and neck width/drop — useful if you’re comparing against a specific tee you already own and love the fit of.

What’s the LURI size chart in inches and cm?

All measurements are garment measurements (laid flat), not body measurements — measure your own tee the same way to compare directly.

A quick way to read this: going from S to 2XL, chest grows by 4 inches total while length only grows by 2 inches — so if you’re choosing between two sizes mainly for a looser chest rather than more length, sizing up won’t add as much extra length as you might expect.

Does Supima cotton shrink after washing?

Cotton has some natural shrinkage in the first few washes regardless of grade — it’s the fiber, not a defect. The way to minimize it: wash cold, avoid high-heat tumble drying, and lay flat or hang dry where possible. If your LURI tee is pre-shrunk or bio-washed, mention that here specifically — it’s a real trust signal buyers look for before checkout, and only worth stating if it’s accurate.
