white dress shirt black slacks The Edward Large = 18 Pants Outfit White Button Up

If you're feeling extra adventurous, build a Tiffany & Co.-worthy backdrop for this classic theme party idea

Occasion: Formal Dresses, Prom Dresses

Black tie optional: the phrase that causes group chats to collapse Black tie optional means the couple would love black tie-level formality, but they are not forcing every guest into a tuxedo-and-gown situation

Crafted with shimmering sequins, this dress dazzles with every movement, ensuring you sparkle all night long

While it would be better complemented by brown, black and tan has its own charm and will look fine if you insist on wearing black shoes

Style with chunky trainers (we're still obsessed with Sienna Miller's colourful M&S trainers) and a denim jacket for unmistakably cool off-duty flavour or with ballet flats and a lightweight jacket for a delicate weekend look
