While a boutique romper is typically a no for black tie events, you can wear fancy rompers to some formal events, including those categorized as “festive.”
Instead of a more casual denim or cotton romper, look for options that are made in dressier materials, like silk, chiffon, or velvet. Also, carefully consider print and pattern to ensure you’re choosing something more sophisticated. Solid, gem tones are a great choice but you can also explore some floral options. Stay away from polka dots, animal prints, and stripes for more formal events.
If you’re heading to a gala or wedding, and your heart is set on a unique one-piece, consider checking out formal jumpsuits instead.
