This is made from a templates I've designed to make a shaped box.
This dress box uses the freehand scallop trim from the template (marked collar B) Signature life paper: Everyday "Be" Living Imprints/Lovely Blue Paper #SG2007
It holds 4 2/8 " square cards perfectly (or standard 4 2/8x5" by 4/8" but the square cards make the box stand sturdier.)
Three are three templates:
1. The first is the dress box pattern
2. The second is the embellishments for the box
3. The last is a for a card that's shaped like a dress (or t-shirt/cut a 'V' to make trousers)
