Once, I was shopping for girls stuff in Sports Authority. I noticed a tall girl (who was definitely a GG) shopping in the men's department. Nothing so unusual, but just from watching her, I got the impression that she was actually buying something for herself that she couldn't get in the women's department because the women's clothes wouldn't fit her.

My wife somehow arranged a surprise all-girl 30th birthday party for me. One of the GGs got me some "sexy" men's bikini underwear. She told me that she was very embarrassed shopping for that. I didn't really understand being embarrassed; as a GG she could be shopping for her husband, son, BF or any man without any suspicion on her. It was all in her head.

Moral. Be confident. Convince yourself that you can shop for anything on the pink side of the store.

As a backup plan, be ready for some funny banter from the SA, like, "I think than will look great on you."

Have a response ready, like:

Oh, you really think so? I do too.

Thanks, but I think it's way to small for me.

or my favorite:

It's for me, but it's not for me.

If the catch the double entendre, this is where they become flustered to talk to you.

And if they're not flustered, then you can talk to them more, providing "Too Much Information."

I've never had to go that far, but I have my script memorized just in case.
