My wife and I had a talk 13 years ago when I told her that I'd like to wear panties. A few days later, we went to Kohl's and I browsed the rest of the store while she picked out a selection of probably a dozen pairs of panties for me. She picked a variety from thongs to hipsters and I was totally surprised just how sexy the stuff she picked out for me was. I modeled them for her and she responded well. It was a start.
Now, I have hundreds of pairs in a wide variety of styles from g-strings to grannies. I have a fairly broad wardrobe overall, but my dressing is mostly restricted to home. But, I wear panties almost exclusively and even in drab, I can just think for a second about what's underneath and there is a sense of comfort and completeness from that.
