Halp! I think I might have just bought a navy 1-button Women's Brooks Brothers Peak Lapel Tuxedo. Button is on the wrong side and the sizing on the jacket and pants is 14. Also the tailoring is a bit funny for a menswear, but it's for a big woman, I can tell you that. Anyway, if anyone has info, I'll take it. Also, if you want to trade, it's available. It's in virtually pristine shape. Warning: Spoiler! (Click to show)
This is clothing 101. Yes, it's a woman's. Hope the store takes returns.
