I have not seen one just like this. I found some similar ones on Ravelry. The Pretty In Pink Sundress, by Jane Davis. The Market Day Dress by Lisa Naskrent. Take a Bow by Candi Jensen.The Seaside Fairy Sundress also by Lisa Naskrent.Another cute one (but not like the one you posted at all) i the Floreal dress by Deanne Ramsey,. I'm not sure if I can put links in here, so I won't even try. After looking at all those adorable baby dresses, I am having an urge to crochet one.
