I’m very much interested in this…
Which variant are you thinking of doing? I know of at least seven: http://th03.deviantart.net/fs25/PRE/i/2008/036/1/a/The_Rise_Of_Supergirl_by_Tompach.jpg
Gonna do this one. Except, I won’t make the S shield so big.
IMO, I think the larger shield looks better than a small one.
Unfortunately, the larger the S shield, the more distortion I get from the boobs.
Perhaps the Clothing Cleavage Modifier would remedy that?
