Classic "tighty whities" jockeys underwear briefs. [ Trigger is: br13f5 ] I use the phrase "br13f5, tight briefs underwear, classic plain white fabric texture, elastic waistband" between 0.6-0.8 depending on the model. If on female adding "cameltoe" helps feminize, or "bulge" into negative. Tends to want to add headband to females likely due to my using 'band' in prompt, so avoid that or add a negative prompt if it matters. Can be used on both male and females, works without altering faces or body types. Feedback and picture shares appreciated.
Description
This version works pretty well but undies can get a bit wrinkly so I add the word "tight" into description to offset this. Otherwise tests have gone well. Feedback and picture shares appreciated. Can be used on both male and females, works without altering faces or body types.
