This almost fits, but I need a cup size smaller. But they don't make a 30C, so I will try 32B next. The few measurements for this bra here indicate the 32 band only stretches a little bit more than the 30, so maybe it will work! Will report on 32B. The bra otherwise fits my boobs great, its very pretty, looks okay (thought not perfectly smooth) under t-shirts. It comes in many beautiful colors!
I ordered this from Zulily, as I thought it was a 30DD. Sizes seemed to skip DD, so I thought it was just an aesthetic sizing system and that 30E in this bra would still be a 30:5. However, I think I am wrong. It seems to be about a cup size too large--I ended up giving to my 30F roommate, whom it definitely fits better but is a tad small. So, I think this bra does probably fit like a true UK 30E.
So comfortable. The stretch lace fabric is super super soft and there's an even softer fabric lining. The wires are a good width on this 30D where they were a bit too wide on the 30E. I do get a little bit of quadding, but that's overshadowed by the floating gore. At the band, it hits my skin, but at the top of the gore, it floats about 2cm away. The band is also very very stretchy, which makes it comfortable but not super useful as a bra. The wires are also significantly shorter than their channels... about 2cm combined (space at the ends of the channels at the gore + at the wings). The shape of the cups is very nice.
Wow this bra is comfortable! The fabric is very very soft and stretchy - I might worry about it stretching out too soon because of the high level of elastic. The wires are quite wide and the band is very stretchy and might run a bit large. On the smallest hook I still have a lot of leeway. The comfortable ness of the cups might make me disregard the fit issues just because it's so soft and nice against my skin. I have no issues with the top edge even with my shallow breasts (often bras cut in). The gore does not tack and seems to want to sit off center. I'm not sure if this is due to the band or cups. The 30d has the same gore issue.
This bra is very nice, soft, and gives good support. The gore is very narrow, with the wires actually touching at the top edge, which I really like. The texture of the lace will probably show a little bit through very thin tops, but it's alright for most of my t-shirts. It feels very delicate, so I'm not sure how long it'll hold up.
