I have a silhouette.
That sounds sort of fashionista-y and maybe a little obnoxious, but it's true: there is a shape that I like my clothing to be, and so that's what I wear. Pretty much all the time, to the near-total exclusion of other silhouettes. It consists of a slouchy top half and a basically nonexistent or very slim-fitting bottom half, and for whatever reason it's how I feel physically comfortable and most like myself.
Like that plaid dress up there, which is actually a shirt (but we won't talk about that): loose up top, nonexistent down below, and there you go: happy me.
