Garden Party semi-formal attire is meant to be polished but relaxed, dressed up for a beautiful afternoon outdoors at a vineyard.

For dresses: Midi or knee-length dresses or a dressy jumpsuit. Florals, soft colors, or earth tones are all welcome. Floor-length gowns aren’t necessary.

For suits: A suit or sport coat with dress pants. Ties are optional. Lighter fabrics like linen or cotton, and colors like tan, gray, or blue, are perfect.

The celebration is partly on grass so choose your shoes accordingly. Evenings in San Diego can get cool, so consider a light wrap or jacket.
