The Kosmos Dress Sewing Pattern Sized 18m-12y

Abstracted into the simplest shapes, this swing dress features an integrated standing collar and cap sleeves add some POP while keeping with the streamlined design. 2 planets (or a planet and a moon) are uniquely added to the dress and wrap around to the back.

This dress is in keeping with the space theme of our original idea with 2 planet-esque buttons in the back for additional interest. Option B eliminates the Planet circles and includes 2 circular pockets. The beauty of this dress is the wide range of options you have in circle and/or pocket placement. Overlap, intersect, eliminate-it’s all up to you.

Partially lined (with an optional reversible full lining), the dress features little topstitching which is in keeping with the minimalistic design.

I love this pattern. It's challenging and exciting to assemble and the finished product is so unique and interesting to look at. I'll definitely be making this again!
