Black cotton triangle bra and thong by American Apparel. I have a whole assortment of black cotton underwear that I mix and match for around the house. Some people have pyjamas, some people have sweatpants. I have ‘lounge underwear’- It’s all black, cotton and stretchy. This bra is pretty awesome at serving this purpose. It goes with everything. Not a whole lot of support but I guess you don’t need much while you’re technically doing nothing. The thong is ok. I’d prefer a brief but all the American Apparel ones are those hipster boy-leg ones and the bikini briefs they have feature cute butt-crack ruching but aren’t hemmed as nicely as the bra. 5/10.
