Briefs on guys are just... icky to me. Even colors other than white do not redeem them. Boxers and boxer briefs!
For me, cotton boy cut or bikini panties preferably with some bows or lace on them. No one sees them but they make me happy. The general store brands are usually some awful colors that I cannot stand with standard elastic band. I really have no idea how they decide the colors and designs for them but someone needs to be fired. So, yea, I have to spend time actually looking even though cotton with some girlie trim on them shouldn't be that hard to find or cost $5 and up per pair.
