Retro Style Navy and White Polka Dots Dress

I got this when I was preggo (never a good idea) but I can't fit into it so never got to wear it :( 're-poshed' in like new condition. Forever 21 sized Medium but with no stretch in the material better fit in the small/medium end I think. So listing as a Small. The pleated 'waist' area is about 28in. Pit to pit about 35 inches. Partial side zip helps with pullover styling. Lined. 100% polyester. I love this style grrrr sad to let it go. From a Smoke and Pet Free Home. Offers Welcomed!!
