Maya, to answer your question (and I don't mind you asking!), my chest is a 32DD (and in some brands, I need a DDD). I generally wear a size 4 and my measurements are 36-27 (maybe 28?)-36. Like many of the others on this thread, I'm definitely curvy, but I'm not overweight. I do think that at some point magazines started using the word "curvy" as a euphemism for overweight. That's not fair to overweight women--it isn't like there is *one* body type for larger women--and it isn't fair to curvy women who are smaller.
Back to brands, I forgot to mention my absolute favorite jeans style: Joe's Jeans in the Honey style. They are the only jeans that work with my butt (which isn't wide, but rather sticks out in the back) and my thighs, which are very muscular. As a warning, they do tend to be very low-waisted.
Angie, as for Pink Tartan and Theory, maybe it does come down to the individual item. A lot of the Pink Tartan pieces that I own are dresses that have some stretch in them, so that could help. But I also own a woven shirtdress, a button-down shirt, and a woven high-necked dress that all work on me. As for Theory, I do find that most of their tops are not cut for a more generous chest. However, their bottoms seem to work with my butt and thighs. I rarely wear pants because I think my muscular thighs tend to look heavy in them, but I do have a pair of Theory suit pants that I think are flattering, and I have a good amount of luck with their skirts.
