I wear women's panties 24/7. Only have a few ond pair of men's underwear and I only keep them for stuff like going to the doctor or the Y.
I like the lacier one's but find most uncomfortable to wear all day under slacks or jeans.
A few month's ago I found some really comfortable Vassarette panties at Walmart. They have a little wider crotch that makes all the difference in comfort, at least for me.
I'm wearing a black pair now under my slacks, along with a garter belt and stockings. I put the later on when I came home at noon from work, taking the afternoon off. I had some errand to run, so on with the stocks! I don't wear stocks during the week to work but do wear them if I work on weekends, which I usually do!
