Geometry Class Dress & Jumper 18" Doll Clothes Pattern

18   |  

You don’t have to like math in order to like this pattern! The dress and jumper have been named in honor of the two geometric shapes they use: a square and a circle. The square neck has an inset panel that can be cut on the bias or straight grain, and the closely fitted bodice is attached to a full circular skirt. As an added bonus in this PDF sewing pattern, two sets of cutting lines for slimmer and those that like candy are included, as well as an easy pattern for a circular petticoat with a crunchy tulle hem for an authentic blast from the past!

Recommended Fabrics:  Dress: Light to medium-weight fabrics with a tight weave and bit of drape. Jumper: Lightweight denim, corduroy, sateen, twill, or wool. It should have some drape. Lining: Lightweight fabric with a tight weave such as batiste or lawn.

Made this out of red

Made this out of red material with tiny snowmen, made up easy and looks good on the doll. I plan to make more using this pattern.

Perfect winter jumper!

Just finished the jumper version in a white baby whale corduroy with a red cherry print! So retro and easy to make up. Took about an hour and is a perfect fit. Well done again Forever 18 Inches!
