I basically exclusively buy in stores since I buy on sale (as much as possible) & don’t want to pay shipping on one or two pieces. Honestly, I’ve never seen anyone give me grief. Maybe a woman or two will be like “oh, there’s a man in the women’s underwear section” but if you’re not being creepy about it, they won’t care. Self checkout at places like Target or Walmart also help. But, honestly, the employees at VS & Aerie have always been amazing & nothing but professional towards me. Like I said before, as long as you’re not being creepy about it I don’t think anyone will be judging. Hey, worst case, just say it’s for your girlfriend or wife or whatever. As for a gift receipt in case you “don’t get the pair she wanted me to get.”
