i think your options are pretty wide open. neutrals, of course, like white/ivory/cream/black/gray. but from the picture, i think that purple, like dark plum, would look good, and maybe other shades of pink/purple. also maybe amber/mustard. are you looking for sweaters or knits like in the picture or would button down blouses work for you as well? is it the whole suit or just the jacket?
i like these from urban:
from anthro
i was looking at printed shirts too...but couldn't really find any that worked fantastically. do you own this or just thinking about it? if you do own it...what to you wear with it now?
