Frequently Asked Questions
Can I wear a midi dress to a formal event?
Check the invitation first. A midi in a dressier fabric with an elegant finish can suit some formal events. For black tie, follow the host’s guidance rather than assuming every midi works.
Can I wear a sleeveless dress to a formal wedding?
Follow the couple’s dress code and venue guidance. If the ceremony asks for covered shoulders, bring a shawl or suitable jacket that works with your dress.
How do I choose a formal dress for prom?
Start with your prom’s dress code, then choose your preferred silhouette. Check that you can sit, walk and dance comfortably before settling on your dress.
