My mother always bought me underwear, white briefs, until I went to university in another city.
From then on, I became the shopper, opting for solid colors, prints, or stripes.
And I started with bikinis, because I've always liked skimpy underwear.
The less fabric, the better!
Later I started wearing thongs and then jockstraps.
Now I mainly wear briefs in winter and lighter underwear (bikinis, thongs, and jockstraps) in summer.
