A gold or metallic sequin dress is pure birthday party energy. Sequins catch light and movement and they read as celebratory and fun. A sequin dress works for someone who wants to literally sparkle at a birthday party. The cut should be simple because sequins are already doing the visual work. Gold sequins work across skin tones and they read as festive rather than costume-like when the construction is good. A quality sequin dress has sequins that stay put and a lining that does not show through. These are the dresses where literal sparkle is the point and you are embracing it fully.
