Loungesuit
Lounge suit means a matching suit with a collared shirt and tie for men. Women can choose a dress, trouser suit or tailored outfit that suits the time of day. It is a common invitation term for business and social occasions. Dressier evening fabrics can work after dark; neat daytime tailoring suits a lunch.

A suit has matching pieces
A lounge suit is ordinary matching suit tailoring. The term describes the outfit, rather than a special garment to buy for lounging. Check the fit of both jacket and trousers.
Use the clock
A work lunch and an evening wedding can share this dress code. Adjust fabrics and accessories to the setting while keeping the outfit tailored.
