I'm a size 6 in UK sizes. I want some t-shirts that are loose and baggy on me, but I don't want them to look stupid because they're too big (I don't want them to be like dresses). Should I get one size bigger than my actual size or two sizes bigger?
Buy a top that is designed to be Oversized, loose and baggy so that you don't look like are wearing something too big. If you want something to fit a bit looser, buy a Size 8 so that it doesn't look noticeable.
