David's not getting the support M3 did, just as Steph doesn't get as much stuff as V3. But they do have some stuff in the David section. Seb, David Diversified, and The Alliance came out recently.

I don't think it would be easy to convert M3 clothing to David automatically. David is based on Steph Petite, not M3. He's more compatible with Vicky's morphs than Mike's.
