I buy all my bras at Victoria's Secret because it's hard to find my skinny-but-big-boobs size anywhere else. I wouldn't jump to the conclusion that this is proof of an OM (unless his credit card was on the receipt?).
On the other hand - most of us here eventually found out there WAS an affair, so if your spidey-sense if telling you something, it may be true. I'd just suggest you have better proof than that.
