When I arrived at the store, I saw a fairly large selection of 30A-D bras. Unfortunately, the vast majority were in 30A-C. There was a small bucket full of 30D bras so that is what I chose to try:
First up is the Very Sexy Push-Up Bra in 30D. Band fits great, not too tight, not too loose. The cups ran true to size too. Nothing to complain about in the shape, all around a solid bra, but nothing special to say about it either.
Next up is the Body by Victoria Perfect Shape Bra in 30D. As Body by Victoria is the Victoria's Secret default line of bras, I was expecting an "almost universal" fit. Unfortunately this was not the case. The band is great, not too loose, not too tight, but the cup shape leaves much to be desired. The top edges of the cups cut into my flesh somewhat. Thereby, I declare this bra not a great fit for tall rooted shapes. If you have short roots this may fit you.
Finally, we have the Dream Angels Demi Bra in 30D. This was the best of the bunch. The band was not too loose, not too tight, and the cup shape fit just right. If you want a good comparison, think of this bra as a version of the b.tempt'd Ciao Bella only better in every single way. The Dream Angels Demi provides a similar amount of coverage, but the underwire doesn't go up nearly as high at the gore. It's more comfortable for someone with low bodyfat and thus sensitive to prominent underwires at the gore. The cups on this bra are also set somewhat closer than the Ciao Bella, so great news for close-spaced and average-spaced people. Finally, the top edges of the cups do not dig into one's flesh! Great news for those of us who may be tall rooted or FOT.
Conclusion: Although Victoria's Secret has been the subject of the bra fitting community's scorn, they have been making improvements in their size range and fit. For many years VS bras have had bands that ran way too large; it seems that with these new 30 band bras they are true to size in the band. The Very Sexy Push-Up provides a "near-universal fit", the Body by Victoria Perfect Shape may be a good choice for people with tall roots, and the Dream Angel Demi is a good choice for people who like the b.tempt'd Ciao Bella but have issues with the high underwires at the gore and far-apart cup spacing.
