These are the garment’s own measurements, not body sizes — and one maker’s medium isn’t another’s, so it’s worth a look before you choose. Soft fabrics never cut quite identically, so allow a little either way.
Width is measured flat, underarm to underarm — double it for the full way round.
How this one fits
Garment-dyed. Relaxed fit, twill-taped neck and shoulders, double-needle hems. Solid 6.1oz weight. The shape is roomy through the chest and shoulders, but the dyeing pulls it in a little, so it lands nearer true to size than the cut suggests. Fully opaque, holds its shape and wears in rather than out.
US fit, relaxed and boxy — but the dyeing tightens it, so it comes up around half a size to a size smaller than an equivalent US tee.
Made for you after you order: 1–5 working days to make, then 3–5 to arrive. Free on orders of £85 or more; £3.99 below that. UK and US.

“I can make a statement without shouting”
Read the full review
This was gifted to me, and it’s now my favorite top. It works as a layering piece over t-shirts and vests, and is particularly good for after a workout or run. It’s very soft, nice color, and the badge is really well made. No one has mentioned it either and I like that I can make a statement without shouting. It’s original. I’m pleased.

“Neither of us had seen anything like it before.”
Read the full review
I bought this for my friend who has recently been diagnosed ADHD. She doesn’t know what to do with the news, so i thought the idea of it being complicated would resonate with her. She was over the moon. Neither of us had seen anything like it before. This is just after she washed it to test the embroidery so it's a bit creased, but the embroidery stayed true.

It’s a comfort colors T-shirt. I have a few already, as I like the feel and the colors are more modern than other brands, and have that lived-in feeling. They remind me of tees I had at college years ago, comfy, relaxed, and easy to wear. Just pick up off the floor and put it on :) recommend.

“It’s soft and smooth; the embroidery is subtle.”

This was a gift from someone who knows me well. It’s very nice. It’s soft and smooth; the embroidery is subtle. The off-white, cream colour is also very handy. I live in a hot place, so I need tees that work with lighter colours too. I would buy more.

Marked “gifted” where we sent the product free. Nobody was paid, and the words are their own.
