This dress is such a darling. It's that perfect, springy shade of blue. This otherwise simple sheath dress makes the neckline the focal point, with its beaded collar detail and diamond-shaped keyhole cut-out. This is also a minor detail, but this dress is sewn at...how do I put this delicately? The bust has pointed seams that are made to accommodate the bullet bras that were ever-so-popular in the 1940s-1960s.
