Hujoo also has a blue and purple, check JunkySpot, I don't know if they're still in stock.
What would you want them compared with? I have a pic of my Mei with a barbie and some other dolls.
It's a comparison pic I took for a friend nearly a year ago:
RS Mei, Barbie, Obitsu 27cm, Obitsu 11cm
And here is a Blue Yu (the lighter blue RS/BBB offers)
The RS minis vary in size though from each body type. My Mei which is single joint is the smallest of my minis. She is very petite and short.
RS Single Joint Female (Mei), RS Single Joint Male (An), RS Double Joint Male (Seng), RS Double Joint Female (Li), Obitsu 40cm (Ai Chan).
Barbie, RS tiny (Yu), RS 1/6 (Bao), Hujoo Berry
The RS's wear Dollzone mini clothes quite well. The boys in the pic are wearing pieces of an outfit each. xD I don't know what dolls you have or their size. D:
(Please forgive all my crap photos xD I'm getting a better phone next month with a better camera so that should be solved then.)
I hope that helps some xD Not sure exactly what you're needing.
