Oversized does not mean size up. This is the single most common sizing mistake, and it is the reason a tee arrives feeling like a tent rather than a relaxed fit. An oversized cut has already added the extra room for you — the pattern is drafted wider through the body, with a dropped shoulder and a shorter, boxier line. Adding another size on top of that stops reading as intentional.
Measure something you already own
Forget what size you usually buy. Take a T-shirt you already wear and genuinely like the fit of, lay it flat on a table, smooth out the wrinkles, and measure it. Two numbers matter most:
- Chest: measure straight across, from one underarm seam to the other. Do not measure around the garment.
- Length: measure from the highest point of the shoulder straight down to the hem.
Compare those two numbers against the size chart on the product page. That chart is the garment's own measurements, so you are comparing like with like. If your favourite tee measures close to a listed size, that is your size.
Why the label size is not enough
Sizing is not standardised between brands, or even between styles within a brand. A regular-fit tee, an oversized tee and a hoodie in the same nominal size are cut to different measurements, because they are meant to sit on the body differently. This is why every Dudle product page carries the chart for that specific style rather than one chart for the whole store.
Reading a dropped shoulder
On an oversized cut, the shoulder seam is meant to sit below your actual shoulder, partway down the upper arm. If it lands exactly on your shoulder bone, the tee is fitting you like a regular cut — which is fine if that is what you want, but it is not the oversized look. If the seam is close to your elbow, it is too big.
Between two sizes?
Think about how you want it to sit rather than defaulting up or down. Choose the smaller size if you want a cleaner line, plan to tuck it, or want the tee to work under a jacket. Choose the larger size if you want maximum drape and a longer hem, and you are pairing it with fitted bottoms that will balance the volume.
Hoodies, crop styles and joggers
The same measure-what-you-own method works across the range, but the number that matters changes. For hoodies, chest and sleeve length matter most, and remember you may be layering underneath. For cropped styles, length is the deciding measurement — a couple of centimetres changes where the hem sits entirely. For joggers, waist and inseam matter far more than the letter on the label.
A note on cotton
Dudle tees are bio-washed cotton. Bio-washing is done before the garment reaches you, which is why the fabric arrives soft and why it holds its shape rather than shrinking noticeably in the first wash. Washing cold and air drying keeps those measurements stable.
Still unsure?
Message us with the flat measurements of a tee you like and we will tell you which size matches it. That is a far more reliable answer than guessing from a letter.
