Inspired by a combo-skirt dress I saw in a catalog, I taught myself a few new things and "unvented" this Sun Dress That Converts to a Skirt ... It is basically three tiered skirt stretched into a shired tube top with straps (elastic in casing). She can also tuck in the straps and wear it around her waist as a longer twirly skirt -- 2 skirts in one!
Easy peasy, tho gathering can be hard on the sleep deprived ma of little ones.
Here is my little she ... in a celebratory run around her room:
And here it is just laid out ... After I made this one, I made three more and it was the better part of her spring wardrobe. Most are now a bit threadbare, paint, mud and other faint prints of being a wee 3YO!
