Nordstrom is a great resource for those of us who want to shop in-store for bras outside of the matrix. In addition to Dillard's and independently owned lingerie stores, Nordstrom offers a considerable selection of bras in non matrix sizes. It is especially notable for its collection of Betsey Johnson bras, which come in 30B-E, 32A-34F, and 36A-E. After boycotting Nordstrom for the last few months (https://grabyourwallet.org/), I have decided to return to shopping there just in time to find a pleasant surprise. Honeydew Intimates is a relatively unknown brand and Nordstrom has been carrying their bras in store as of late. They come in matrix sizes (32A-36DD) but they also offer 30B-30DD! This great news for us gals who need non-matrix sizes. Their aesthetic is youthful and cute, much like Betsey Johnson, b.tempt'd, Aerie, Cleo, and Curvy Kate. They have a mix of wired and non-wired bras. The wired styles are all moulded, some push-up, some non-pushup.
I tried a bunch of their bras in 30D, so let's take a look at some of them:
Skinz Underwire Push-up Bra - standard moulded push-up bra. Works for shallow and broad rooted shapes. I quadded out of the top edges again, might run a bit small in the cups.
Camellia Underwire Balconette Bra - this one is a similar fit to the Betsey Johnson Starlet Lace. The band is noticeably tighter than other Honeydew bras. It feels like a Gossard 30 band honestly. If your snug underbust measurement is 28" or under, this might be a good one for you. It is a tad bit shallow for me at the bottom parts of the cups. Again, I quadded out of the top edges.
Conclusion: Honeydew Intimates is a good brand if you have a very shallow, and classically broad rooted shape that is common amongst people with small breasts. It is too shallow for me, but my shape isn't extremely shallow. Their bras might all run a bit small in overall cup volume. If you are in between cup sizes, size up.
