amen!
i got sicky of the flowy dress trend awhile ago too and had a really hard time finding body conscious fits on the cheap, so i bought alot of d&g for awhile. for under $100 my best suggestion is bebe. i got a really cute roland-mouret-ish dress there a few months ago on sale for $69!
i'm also pairing slim pencil skirts with fitted tops for a similar effect.
