Light Blue Prom Dresses

From pastel tones of baby blue to light blue long prom dresses, this color-curated collection marks the 2025 season with tonal elegance. Below, you’ll find iterations of light blue prom dresses that appear with a modern undercurrent, reimagining occasionwear codes with thoughtful vision. The light blue prom dresses are created from a series of luxury textiles, with languid silk, elegant linen, flowing chiffon, and cascading organza materials that are contrasted by form-fitting textiles — think knitted jersey, structured crêpe, woven jacquard, and the four-way support of our revered Compact Stretch. Appearing in a myriad of silhouettes (with light blue short prom dresses offsetting flow-length pieces), find your bespoke piece from the portfolio below.
