Zimmerman, if you're familiar with the brand, runs very small. I always order up two whole sizes with this designer. I bought the Pearl-colored top in a size 2, and it was the right size. Beautiful and elegant. I lucked out with the last blouse available.
Shopbop, however, delivered it in such a poor manner. The silk blouse was rolled up in a ball, in a plastic bag, without any care or concern for the material. It arrived needing a visit to the dry cleaners. Awful shipment procedure... not sure why they're failing with packaging and delivery in the last year. Designer coats/dresses do not come with garment bags for at least a year now. Silk blouses are rolled in a ball and put in a plastic bag. Terrible. They need to revert back to their old high-standard policies of packaging, shipping, and providing excellent customer service.
