Olivia runs very snug and small in the cups, definitely more like a 28C. It's pretty and youthful, though and the embroidery is actually quite nice in person, even though it looks odd and metallic in pictures.
It seems both the band and the cups run small on this bra. Fits like a 28C, really. The embroidery is noticeable under t-shirts (my nips don't show but the embroideries do..). The metal(?) ring pieces that connect the straps creek. The straps are thin.
This bra runs a band size small and a cup size small, at least. I ordered a 30D and the band fits like a 28, while the cups fit a size small. It's a little difficult to judge but I'd say this fits like a 28C or D. The wires are also very wide, and so are the straps, though they're connected sort of inward on the cups in the front. I wish there had been reviews of this bra so I could've ordered a size that would have worked for me (probably 30E?) because it's quite comfortable and has a nice structure to it for a unlined bra.
