Help me: The hunt for a tunic dress

I've always loved the look of cotton tunic dresses.  They seem very Palm Springs elegant to me, and I think I'd feel very fancy (but comfortable) wearing one.  However, I'm having a lot of trouble finding one at a decent price.  Every one I like is around $200, and I will not pay that for a dress

What I'm looking for...

Any ideas where I can find this look on the cheap?  I've checked every store I can think of and haven't found one... this doesn't happen often!

This is the closest I've found ($48 at Kohl's) but it doesn't have the 3/4 sleeves I'm looking for

Update:  I found this dress on hsn.com but I'm just not sure.  Judging from the size charts, I'll need to order big and then have it taken in.

Surely there's some sort of Lilly Pulitzer/ Tory Burch knockoff out there.  Help me find it!
