I'm desperately seeking a dress for a work-related event next month, I feel I've been to every online outlet I can think of as well as spending hours trawling the shops, and I just can't find what I'm looking for. I want a knee-length, shift style dress, ideally with a defined waist/belt, and not black - blues/greens/purples look best on me. I don't want it to look completely plain, so either a pattern or some sort of textured material would be best. Has anyone seen anything remotely fitting the bill? Budget is about £100.
