Dressy Casual to Semi-Formal.
The wedding has a spring floral theme.
Dressy Casual: Special event clothing that's relaxed and comfortable but still polished. Men consider dress pants and a button down dress shirt, tie optional. Women consider elevated sundresses, jumpsuits, dressy pants with a blouse and blazer.
Semi-Formal: Polished looks like a suit for men and dresses, jumpsuits, or smart separates for women, with emphasis on elevated fabrics, tasteful colors/prints, and sophisticated shoes. Men consider suits or blazers with slacks. Women consider midi-length dresses, jumpsuits, and suits in elevated fabrics.
