You are not alone. I have found that black underwear is still a popular choice. You pick out a pair from the drawer, dress yourself, and go about your day.
I have found out that there is a new brand that would offer only briefs, trunks, and boxer briefs in black: Apixt. The brand has a Kickstarter campaign. The campaign has a US$3,000 goal, with a May 21, 2021, deadline.
What Makes Apixt Special?
The underwear is designed to feel like a second skin.
Environmentally sustainable fabric: made from the hulls of soybeans.
The underwear is made in Europe, with SILVERPLUS technology.
