Asian cotton underwear brand suggestions

Hi my waist is 23”. I’m 4’11” and Im struggling to find cotton underwear that doesn’t sag at the butt lol

I tried the smallest size Hanes, some online independent brand, and I like targets cotton blend underwear but they only have them in like black and a couple nude shades.

Lately I keep hearing a lot of Asian clothing companies are sized smaller. I am in the US if that might be an issue with shipping
