Birthday Dresses

Mark the moment with refined appeal after browsing our celebration-ready curation of birthday dresses. This party-appropriate edit merges fashion-first influences with an essence of elevated design, ready for your 21st, 30th, 40th and beyond. The timeless black birthday dress is contrasted by a bold curation of colour that will keep you in the spotlight, with bold brights, aquatic blues, delicate pastels, zesty hues, and plenty of patterns and prints — with florals, geometrics, tropicals, stripes, and watercolour gradients. Pick your birthday dress from mini, midi and maxi lengths, appearing in an array of styles. Find elegant birthday dresses crafted from silk, satin and chiffon, as well as sculpted silhouettes in our revered compact stretch fabric, jersey and structured crepe fabric. Our classy birthday dresses appear with an artful series of finishes; featuring glittering paillettes, floral-inspired rosettes, beaded tassels, geometric crystal embellishments, diamante and faux pearl fringing, inlaid sequin stitching, feather trims, ornate floral jacquard, intricate embroidery, and metallic stitching that flows on the form. Shop birthday dresses for women below.
