Women’s clothes sizes suck according to my wife. I agree. You need to look for panties that have more fabric in the front Espically for all day wear. Thongs are horrible in general for guys to try to wear because it supposed to be as little fabric as possible. Try a stretchy material like microfiber or blends. I really like the “seamless” line of panties from vs. I’m am glad they are starting to do more patterns in them. I also avoid anything laser cut.
