You'll be making sure your debut gown matches your chosen theme, and surely, you'd want your guests to dress appropriately, too. Check out our list of dress codes to find out which one suits your party.
If you want your debut to say "all grown-up," go for a black tie affair. Ask the guys to wear three-piece suits (shirt + waistcoat + jacket) or tuxedos. The girls are expected to wear full-length gowns. Of course, make sure that your chosen venue is well-ventilated so guests can still be comfy in their ensembles.
A formal dress code is very similar to the black tie, but a bit more laid back. If you think a super strict dress code won't sit well with your guests, you can opt for a formal dress code instead. The girls can pick between evening gowns or shorter ensembles. Midi dresses can be acceptable in formal affairs if they're made of fancy fabrics, like lace, satin, taffeta, chiffon, and shantung silk. The guys should wear suits, but waistcoats aren't required.
If you want your guests to look sharp but not too serious, go for a semi-formal dress code. Girls can wear midi to short dresses in dressy fabrics. The guys may don nice trousers, long-sleeved button-down shirts and ties--they may leave their coats at home.
To complement your laid-back debut, you may implement a smart casual dress code. The smart casual dress code may be challenging to pull off, as some guests might take the "casual" part a little too seriously. However, just remind them to steer clear of anything denim. Instead, girls can go for summer dresses in light fabrics, or dressy trousers worn with blouses. The guys can wear trousers in cotton twill fabrics, and short-sleeved button-down shirts.
When you've determined your dress code, don't forget to inform your guests (giving them a moodboard of the recommended attire helps). For a fun flair, you may incorporate your theme in the dress code, too.
