Peter Pan collar dress, purchased from Modcloth in 2014, has stretchy fabric and a sturdy zipper in the back. I wore it twice, and it has been washed. It comes from a smoke free home. It was in a home with a dog, but it hasn't been for over a year. Bust: 32"-37" Waist: 26"-29" Length: 31" Sleeve opening: 11"-13"
