The last time I was measured, the woman at Nordstrom's insisted I'm a 34B and the woman at VS said I was a 36A. But I find both sizes to be too tight. They might seem okay in the fitting room but after about an hour I can't stand them anymore. The woman at Nordstrom's refused to believe that I could not wear a 34 band. The woman at VS was much more understanding, but she didn't have any 38s in small cup sizes (I would need AA and they don't even have A).
Also I can't wear underwires because they dig into the front of my rib cage. Very painful.
I went to a local specialty store and bought a bunch of "spa bras" which are 1-size-fits-most with wide bands and cookies to which provide a little more volume and hide the headlights. They're pretty comfortable, though I get tired of having to position the cookies every time I put them on. They don't provide any support so they wouldn't work for someone who needs a larger cup size.
I also have a some Barely There unpadded bras. They used to be available in 38A, and I have several of those, but a couple of years ago they "improved their sizing" by switching to S-M-L. The large is a little snug in the band but they're cheap and come in fun colors so I bought a bunch a few months ago. They stretch enough to be comfortable on most days. I use Bezi bra discs with them when I'm wearing a t-shirt or thin sweater.
BTW the woman working at the specialty store was great. She understood that the tape measure only gives you a starting point, and somehow she managed to make me feel good about my figure. Whereas the woman at Nordstrom's had me in tears, feeling like a freak.
Also, when I was trying on 36As in VS, it was interesting that some styles came closer to fitting than others. I learned from the saleswoman that the front of the band (between the cups) is supposed to rest against your skin, but one style left a gap which indicated it didn't fit right.
