I have patterns for Dress Forms - http://www.lynwaring.com/mfd.htm - The originals include 3 female and 1 male. There are also 2 individual styles available Fluer (female) & Baxter (male). I created these patterns many years ago so that my creation look more stylish. To me, 'half scale' dress forms look a bit 'clunky' - so I created the shape to suit 'my look'! In 2000 I was asked to create a dress form pattern for Barbie - I did and now I have 38 additional dress form patterns for Fashion Dolls. You can check my collection at http://www.lynwaring.com.

If you are interested I think the patterns for Kaytie or Soozie are the best proportioned dolls!

Hope this helps!
