Sequin dresses are the most joyful category of clothing. Full stop. They make sound when you move. They catch every light. They photograph in the most extraordinary way. They have a festive quality that makes any occasion feel like a celebration. We take sequin dress selection very seriously despite the inherent silliness of that sentence. These are the sequin dresses that have the right density, the right drape, and the right colour to look genuinely glamorous rather than chaotic. The ones worth every sparkle.
