Love both pieces! Is the dress Vince Camuto?
Ladywone: The Nordies on Michigan Avenue is great. Encore is the name of the Plus Size department, and Point of View carries misses sizes in Halogen, Vince Camuto, etc. I usually start in Point of View when browsing nordies. The purses and shoes are amazing, too. You might also like the Rack that's further north -- near Water Tower. It'll feel a bit like upscale Thrift shopping!
