For my granddaughter's fifth birthday, I remembered a cape I had made more than 30 years ago, which now lives in the "dress-up" box. I resurrected it and got some fabric to match. I made a top and pants from crinkly cotton (the kind that fits when you put it on and two seconds later is big enough for two of you--oops, should have made it a lot smaller).
Back neck opening loop made on the serger; clear button so I didn't have to try to "match" the fabric, which might have been impossible.
and the pants
Top it off with the cape (awesome fabric!)
Complete outfit--although I'm not sure she noticed it...
Outfit accomplished! (except for the massive stretching, it works well and will be nice in the summer evenings)
