They seem pretty true to size (I'm a size 6 to 8 and everything I own from New Look is a 6 or 8 depending on how loose I want the fit) on basic tops, dresses and trousers. The only thing I've found is that the waist on things is quite big, When I've been trying to find crop tops a 6 might fit my chest but it's baggy on the waist. Same with skirts, I got a size 6 petite one and it's too big, so if you like fitted waists then go down a size (unless you're a 6 in which case...you can't)
