There are some breast reduction morphs for Vicky in Free Stuff. Not sure which version, or if it works on all of 'em.

The character I want breast reduction morphs for is Laura. She's supposed to be a kid, but she doesn't have any "smaller breasts" morphs. Just morphs to make her boobs bigger. She should have morphs to make her flat-chested, like the preteen. It's easier to make Stephanie Petite flat-chested than Laura. Which is weird. I really wish DAZ had included a "no boobs" morph. That way, at least some clothes would support it.
