I was petrified at buying panties and such until I was in a Walmart that had a self check out. I had other items that I scanned and it worked out great. I finally got up enough guts to take some panties and hose (along with a few other grocery items) to a check out stand where a lady was working. I braced for being questioned and to my pleasant surprise she didn't even look up.

Since then, I have gone to major department stores and bought whatever I want, but I am careful to select a check out with a mature lady cashier.
