Cocktail As our wedding in Buenos Aires is a spring evening with a rustic, white-accented vibe, please wear cocktail attire: semi-formal dresses, jumpsuits, or dressy skirts for women; sport coats or blazers with dress shirts and tailored trousers for men. Comfortable, polished shoes are recommended—the venue has some outdoor areas and uneven ground. Lightweight fabrics and breathable layers will keep you comfortable as temperatures cool after sunset. If you plan to dance, consider bringing a small shawl or wrap for the breeze.
