As a size 6 (and on the small size at that) with a tiny chest, even I found the XS a bit too snug so maybe try a size up if you're devating which one to go for. I'm going to have to return mine which is a bit of a shame but otherwise a lovely top.

The description states the model is 5'7 and wearing an XS, I am 5'5 and very similar build but I ordered a Small just to be safe and it is so unbelievably tight that I could not breathe and the lining of the padding was showing through. Other than that, the colours are nice and the material feels like it could be comfortable if the sizing was reliable with the size guide.

Not the quality I was expecting and the colour in reality was much different, rather on the large size also for a medium.  worth spending the extra and going for a better make like gymshark

Great fit, size as expected, lightly padded and pads are not visible on the outside. Look great with matching leggings.

Love this bra, really well made & a lovely colour. Gives good support. I’m a size 4/6 and it’s slightly large. But I can live with that.
