A garden party–themed cocktail dress code is all about polished elegance with a fresh, outdoor twist. Think classic cocktail attire softened by light fabrics, cheerful colors, and romantic details. For women, this might mean knee-length or midi dresses in florals or pastels, dressy jumpsuits, or flowy silhouettes paired with heels, wedges, or dressy flats. For men, a suit or blazer with dress pants is perfect—lighter shades like gray, tan, or blue are especially fitting—paired with a collared shirt (a tie is welcome but optional).

Overall, aim for refined but relaxed: stylish enough for a celebration, yet light and comfortable for an outdoor setting surrounded by greenery and blooms.
