A blue evening dress is the most flattering, most photogenic thing you can wear to a formal event, and arguably the most memorable. Blue suits every colouring, it photographs beautifully under low lighting, and it has a shade for every mood: soft ice, pastel, powder and sky blue for something romantic, rich royal, cobalt and electric for jewel-tone drama, and deep navy and midnight for pure elegance. In luxe fabrics like satin, silk and velvet, a blue evening dress reads expensive and effortless. Our edit covers every shade and length, in sizes 4 to 20, with free UK delivery over £135.
Why blue belongs at black tie
Black is the obvious choice for a formal night, but blue is the quietly clever one. It brings colour and a sense of occasion without shouting, which makes it perfect for a ball, a formal dinner, an engagement party or a milestone anniversary. Navy in particular is a brilliant pick for an evening or winter wedding (it is one of the most-loved guest shades and stays well clear of bridal white). Style your blue evening dress with elegant heels, a clutch bag and your choice of metal: gold jewellery warms up navy and midnight beautifully, while silver sharpens cobalt and ice blue. Keep everything else simple and let that rich blue do the work. For a cooler venue, a wrap or tailored coat finishes it without losing the elegance.
Ice, royal, or midnight blue?
Blue gives you more range than almost any colour, so you can match the shade to the formality. Soft ice, powder, pale and sky blue feel ethereal and romantic, lovely for a spring or daytime-into-evening event. Royal, cobalt and electric blue are the jewel-tone show-offs, made to stand out under the lights. Navy, midnight and slate are the deep, grown-up blues that rival black for elegance, especially in velvet. Then there is length: a blue maxi gown is the move for black tie, a blue midi suits a semi-formal evening, and a sharper blue mini works for a cocktail event.
