Ruffled Sun Suit Romper

I bought a pattern from LittleLizardKing on Etsy for this fun little romper! (The first two pictures are from the pattern and the next two are what I made).

The pattern was very easy - the only tip I have is that if you hate raw edges as much as I do you may want to serge the top raw edge of the ruffle before you gather the ruffle. You only see it if you lift up each individual ruffle so it isn't a big deal but still...

I want to try to modify the pattern to make a reversible lined romper without ruffles!
