I usually waffle between a 32E and a 32F (for the larger side), but the initial 32F I ordered was actually too small. Returned it and sized up to a 32FF which was much better... so I would absolutely SIZE UP IN THE CUP as the description suggests. With the proper size, the cups give a nicely rounded shape under shirts, although (as with all cut and sewn bras) the seams are prominent. The top edge of the cups isn't forgiving, and can cut into your tissue if you have high "roots" (and, I would imagine, full-on-top breasts too). It hugs my larger side pretty well, but it "bubbles" or "puffs" away from my chest on top, as that side is more of a slope shape. It's a little embarrassing as a reminder that my boobs are really uneven, but the overall support wins. Plus the lilac/lemon colorway is GORGEOUS, spring-y, and feminine: everything I love in a bra! Those stiff cups are for a limited range of shapes, though, so I would keep that in mind while ordering. Again, SIZE UP IN THE CUP!!!!
