So here is what the dress is supposed to look like:

And here is my version of it:

It's unusually flattering, so I'd really like to keep it--trouble is, it is a little bit short (just above knee length) without that third ruffle on the skirt. I'm thinking of making another ruffle, but I'm scared it would be hard to match. Would a contrasting ruffle (I'm not sure what color!) work, or should I just leave it as is?
Thank you for your help!
