Pristine in the palest blue with a minimalist aesthetic, this gown from Rebecca Vallance places the emphasis on flawless fit and elegant design. It's impossibly flattering with a squared neck and cap sleeves, while its hourglass-enhancing shape, side slit, and trumpeted hem cement its statuesque status. Play up modern glamour by adding a single bracelet and tall sandals in shimmering silver to complete your look.
