Female underwear that roughly follows the coverage of male briefs. Illustrious already knows “boyshort panties” (come to think of it I never tested Pony but not reason it would be better), but it covers so many things (including longer leg variants) and is so thinly tagged the results are all over the place.

Trigger: be_bo_p
Support: crotch seam (it's an existing tag!), panties, [color] waistband (not trained with, but Illustrious understands it)
Negative: bow panties, lowleg panties (ILXL and PDXL need these for panties regardless of type), clothes writing (if it pops up, shouldn't be needed otherwise), realistic, photo (medium) (shouldn't be an issue, but if they are use these)
Do NOT use: boyshort panties (base understanding is all over the place so just skip it)

No changes from Illustrious
