Went a little OTT with the Easton shirt in size 42 (US 10) I just got yesterday. It matches a ton of stuff and is light for summer. Molly Goddard skirt in a size UK 16 (US 12).
I'm 5'10 and 180lbs. Usually wear size 10/XL.<abbr>Sezane,10,$130,5'9-5'10 5'9-5'10,Button-Down Shirt,French Brands,Size 10,Skirt,Tops All Reviews,Sezane,Skirt,Top</abbr>
