Okay, I cleaned out all my earlier experiments and began again. These are medium quality conversions of Taruru's neat AD&MD 01 Set. I had to push socks', then shoes' poke-through settings to ~0.35 to fix heels of socks, then sides of shoe, but shirt & skirt worked on default. Wig is P4 'curly woman', briefs are P4 bikini bottom.
Couple of thoughts...
Killing a holey RSR means closing
Poser, zapping the RSR, re-opening
Poser, setting up figure & costume again. This really, really slows work-cycle, so I'm going to suggest a 0~~9 incremental counter.
Current C-D 2.7 has no specific morph for feet. IMHO, it should.
I could have made shoes and socks fit much closer if I ignored the small poke-throughs in socks' heels...
