Sweaters, sweaters, sweaters.
If you aren't making them, you should be.
Again, find lightweight human sweaters and knits, slice and dice and re-make into doll sweaters.
That is the science of making doll sweaters without knitting/crocheting them yourself!
Chunky, textured, striped.
Oversize, over the butt.
Embrace your inner sweater-lover!
Forever21 is great for full ensemble inspirations.
