Search Results: not wearing panties

So I went clothes shopping with a very good friend of mine and we were picking out a bunch of clothes to go try on. There was a good sale on panties so we grabbed some as well. Normally stores don't let us share a room but there was no one to stop us. We are very close so it doesn't matter. So we were trying on the clothes and she got to the panties well she precedes to take off her pair and try on a pair. I always try them on over the pair I am wearing to be sanitary like I thought everyone did. I told her that its nasty and she said everyone does it how else would you know they fit right. The worst part is two of the pairs were thongs.

She said that she keeps clean and its fine but I asked what if someone before tried them on and they were not clean. She just said that is would be fine and she didn't care.

Is this really how other girls try on panties? I also wear my underwear trying on swimsuits.
