A silk blend wrap dress works because it solves the actual problem of needing to look put together while being able to adjust the fit to your body. The wrap detail means the dress works for multiple sizes and the silk content means it drapes and catches light in a way that plain cotton cannot. Wrap dresses read as effortlessly styled which is the whole point of dressing for office events. The silk blend is usually enough silk to get the benefit without the price tag of pure silk. These dresses move well and feel good on and photograph well under indoor lighting. A silk blend wrap dress is the piece that makes you look like you have your life together without requiring that you actually do.
