Kowtow black long sleeve shirt which is 100% cotton. Has a slight asymmetric seam detail! Doesn't make it sit differently on. Size L on the tag, however, I am a size 12-14 and don't like how it fits. I personally suggest this as a 8-10, or a 12 with a more narrow arms if you want a fitted tee. Happy to send measurements. Bought through Kowtow via their reloved programme and gutted it doesn't fit! Their sizing is inconsistent. Thank you!
