I love the Joules Harbour tops.. They're the thickest ones I own, and I own waaaay too many breton tops. I wouldn't size down, but I don't like my clothes tight, they're a flattering loose fit. And good price for the thickness of material for Joules. I bought the tee version last week and going to send it back as the material is awful, and it was only £5 less!! You get the Harbour top in long and 3/4 sleeved versions.
