>>1872485There is definitely a system to the best underboob imo:
>clothing draped over tits, not so tight it looks glued on, gives it a more risque feeling>big tits are better for underboob as they don't require the clothing to be obscenely small>instead of showing the nipples outright, look like it's a situation that comes incredibly close to doing so, or just barely does>any angle from below the girl's breasts, this includes her jumping up, leaning forward in front of you, or turning over onto her side while laying downWhat makes underboob so great imo, is the high chance of boob slipping out or catching a glimpse of nipple.
Likewise, flat chest does down-blouse the best for the same reason.
