I'm going to treat myself to a black silk shirt - to wear with jeans, coated jeans and with slip skirts. I've tried a size 10 which is the sort of look I'd normally go for - a bit fitted but not at all tight. But in some ways the size 12, which is baggy, looks good too, as the oversize look tucked it in the front seems more current. It is expensive, so I don't want to make the wrong decision. Has anyone got any thoughts on the best fitting to get?
