School Formal Dresses

Q: What should I wear to a school formal?

Whatever makes you feel amazing, within the dress code. School formals usually lean formal or black-tie, so think a floor-length maxi, a midi , or a dressy mini if that’s more your thing. Satin, lace, sequins and corset styles are all classic formal territory. Check whether there’s a theme or a colour everyone’s steering clear of (looking at you, white), then pick something that fits the brief but still feels like your taste. When in doubt, a little more glam is never the wrong call.

Q: How formal is a school formal, exactly?

That comes down to the dress code on the invite. ‘Formal’ or ‘black tie’ means go all out, floor-length or a seriously dressy shorter style. ‘Semi-formal’ is a step down, so a cocktail-length dress or a smart mini works. A leavers’ ball is usually the dressier end, closer to black-tie. If the invite doesn’t say, ask around, your year will usually land on the same vibe. And when you’re unsure, slightly overdressed beats underdressed every time.

Q: Can you wear a short dress to a formal?

For sure, a short dress can absolutely be formal, it’s all in the fabric and the styling. A mini in satin, sequins or lace with heels reads just as dressy as a floor-length gown, and it’s a lot easier to dance in. Maxis bring the classic drama, midis sit somewhere in between. Go with whatever suits you and how you want to move on the night. Short and glam is a very valid formal choice.
