For me, the secret is how they feel on me. I want to feel feminine underneath my clothes. I have mail parts down there, so I don't like underwear that remind me of that. So I go with fairly low cut satin panties most days. I do have a few Lacey pairs that I like too.
If , I'm feeling a little edgy, I have a pair that feel like black leather, A very thin, small white pair, And of course, leopard print.
If I'm wearing a tight dress, then I will opt for gaff underwear.
