This is what I whipped up.
It's for a sweet little girl named Emma. She and her lovely parents were gracious hosts when I went out to NJ for a wedding earlier this month.
Pattern: None. Just a basic little bodice shape with armholes, tying straps and a long rectangle for the skirt. I went straight to cutting/eyeballed everything. *hopefully it'll fit--at least until the weather gets cool. The bodice is a double layered, and the inside layer is slipstitched to the skirt. If you wanted to make the skirt a double layer, the dress would be reversible.
Material: < 1/2 yard cotton gauze and seersucker from my stash.
Time: Quick! About 2 hours start to finish.
