Holy shit.
When our DD was born, a coworker of DH's -- a truly lovely older woman -- gave her a super-fancy dress, like something you'd see a Victorian doll in, with petticoats and lace and everything. Except it was totally not anything that we'd ever put on our kid. So we debated whether returning it would hurt her feelings, but decided that was the better option than leaving it untouched in her closet.
Imagine my surprise when we discovered it was a $150 dress. I wouldn't buy my own kid a $150 dress, much less someone else's. We got several useful (and IMO much cuter) outfits from the return, even at the "boutique" prices.
