Heh, cute story.

Today we had an amusing (sort of) experience at Nordstrom. It wasn't in our original plans for being at the mall, other than "oh yeah, we were going to go check out underwire bras now" sort of thing.
The lingerie section was rather busy, and it took me a while to realize there was an annual sale going on. Since our previous visit (1-2 weeks previously) had been a bust (no pun intended), I wasn't holding out much hope.
So we started browsing the racks. Err, the displays.

cherri found a couple of dainty, lacy numbers which were conceivably in or close to her size, but she eventually put them back.
Not far from there, I found a bunch of Fantasie bras (there was no obvious Fantasie sign there). Hopes suddenly raised, I started to browse. They were all beige, so I focused on size only. Found one that looked reasonable (going from memory, it was maybe a 38G), but I put it back on the rack after cherri found a 38G by Le Mystère in red that she rather liked the look of.
On my way to meet back up with her, I discovered that a sales rep had separated her from the rest of the women, and was taking her off elsewhere to a less busy cash register.
As I was headed back to meet up with her, I'd noticed a rack of blue bras (or what the manufacturer calls "corn blue"), so I asked her if she was interested. She was, so she slowed down her advance to the register while I dashed off to see if they had it in her size.
By this time, the sales rep had caught up with me and started spouting off things like "oh she probably needs to be in a DDD or maybe F-cup, blablabla". I'm thinking to myself, you clueless twonk, I know what the fuck I'm doing here. I think she ended up pulling a 40E off the rack and followed along with me to meet up with cherri by the changing rooms. We handed cherri both the 40E and the 40G and cherri headed on inside. Somewhere in the dialogue, the sales rep asked cherri if she'd be interested in black, so she went off on a quest to find something apropos.
Oh, I almost forgot to mention! I don't quite recall at which point (I think it was while we were standing in front of the "corn blue" bras), but she tried to "educate" me, saying "by going up a bandeau size and down a cup size, it's exactly the same." I could feel myself quietly smouldring inside, wanting to scream at her what a disservice she's doing her customers by perpetuating that lie. But I held my tongue.
While cherri was in the changeroom, the sales rep swept by me and tossed out, "I'm just going to measure her" and off she went. Again, eyes quietly rolling inside my head.

At some point during our dealings with her (after the "measurement") she said to me with a straight face (and cherri standing right there), "Your wife is a 38H," to which I replied with my best I'm-dead-serious-when-I-say-this voice, "I knew that." Maybe she was expecting me to reel backwards in amazement or something.

[cherri told me later that as the sales clerk was measuring her, she commented "oh, your current bra seems a bit small in the cup, you might need to go up a cupsize... what size is the bra you're wearing?" to which cherri replied "36H", to which the clerk replied with a startled "OH..." and that was pretty much it for the measuring session.

Oh, she did say something to the effect of "I never would have guessed, I'm a 40H myself." To which I told cherri, "Her? A 40H?? HAH! She's a BBW
*, my guess is she should be wearing a 46B." Seriously, I tried to size her up a few times, and... well, there's just no bloody way that she's a mere size or two in bandeau away from cherri, and her boobs just weren't all that distinctive from the rest of her. Okay, maybe I'm being a little unkind; it's possible the clerk could have been a C-cup.]
I was still standing around outside when the clerk cruised past me again, this time saying "one of the blue bras fits her great!" The fact that she didn't say "the bra *I* suggested fits her great" told me that it was the bra that *I* selected which fit her better than *her* choice. Twonk. I still think a 38G would have been better than the 40G, but... okay, now I'm not sure why I didn't pull that one off the rack to send in with her. Argh. Anyway, cherri said the blue bra feels like it's not even there, so that's good in one sense, but questionably so from a breast support standpoint.
At any rate, I feel vindicted. Skadoosh!

And yes, the red, black and blue bras look fab on her.
* and I'm not just talking "a few extra curves here and there", folks; I'd be surprised if her BMI wasn't at least 35.
