Not a huge deal, probably, but given the context, it was a huge deal for me.
Last night at a fancy concert, I ran into an acquaintance of mine. She has always been dressed appropriately, never once seen down her shirts/dresses, never once seen an ooops of any kind, never even seen a bra strap out of place. Very professional; her life depends on it.
Last night she was at the concert with a client and his wife (no, nothing naughty), and I noticed her amazing dress. Low cut, but fit well. I immediately had the thought I usually do: "It looks appropriate standing up, but what happens when she bends over?" (I am assuming I am not the only person who thinks this most of the time?)
Anyway, JUST as I thought that, she bent over to show my wife the super fancy detail at the bottom of her dress (we couldn't care less, but it fits the woman's priorities to show people, I guess). Despite the front being very low-cut, she actually had a bra on (I have no idea how, but she's always been able to pull miracles). BUT, both cups gave way a bit and I saw her amazing nipples. Very dark. Permanently erect. Tiny areola. With her extremely pale skin, I was shocked at the darkness. They also pointed way off to the side far more than most.
The client and his wife were looking, too, and the wife gave the client a smirk of "go ahead, you already saw them" when I looked for her reaction.
Given the decades I have known her on and off and never even seen a bra strap out of place, my heart was thumping so hard that I almost passed out.
Again, not a huge deal, but given the context, for me it certainly was!!
