Underwear trouble

I want to be able to wear cute underwear instead of the granny panties out of the pack but I’m pretty susceptible to UTIs and have to wear cotton underwear. I haven’t had much luck finding anything that’s cute and practical for my situation. Has anyone had any success with cotton underwear that doesn’t make you look like a toddler switching over to underwear from diapers for the first time? (I’m also plus size so that adds to the difficulty of finding clothing in general)
