Hopefully this is in the right place! I got my first vinyl doll a month or so ago from the Volks USA store, a Dollfie Dream Pretty with the default bust. She's my first 1/3 scale doll and oh my GOSH is she fun to sew for. I've been using a lot of Requiem Art 1/3 Curvy patterns, printed at 85% scale, and so far they're fitting great.
Here's her Qipao pattern on Yoko. If I make it again, I'll decrease the size of the bust darts. I didn't take the waist in because Yoko's supposed to be about 14 and I didn't want her dress to be too tight.
