I bought this hoodie in a size L (16-18 on the size chart) as I'm a standard UK 18. I'd read the Q&A and as Skinny Dip said to stick to your true size, I did. But when it arrived today I found that the hoodie was not oversized in the slightest, though it does fit me. I wanted it to be baggy, but it fits like a standard hoodie. Beware of this if you're on the bigger end of the dual sizing range on the website. The quality is good and it will be a very nice, warm hoodie for the autumn/winter time.
