* Please note, these offer loose equivalences between the 'oversized’ items and how they translate into UK women's sizes. These sizes will allow for a couple of extra inches, so that they maintain an oversized fit.
For further guidance, I thought it might be useful to give details of my own sizing.
I usually wear a UK Size 12 on top and would wear the following:
Fitted T-Shirt: I wear a Medium for perfect fit, or a Large for a looser fit.
Oversized T-Shirt: I wear a Small for a 'just right' oversized fit - looks good tucked into jeans, but not so big it looks like a pyjama top!
Sweatshirt: I wear a Small for a perfect fit, or a Medium for slightly oversized.
