Garden Party Formal is a dress code blending elegance with outdoor comfort, meaning polished but relaxed semi-formal attire with lighter fabrics, brighter colors, and floral patterns suitable for a garden setting, less rigid than traditional formal wear but more dressed-up than casual. Think floral dresses, lightweight suits, jumpsuits, and dressy separates in breathable materials like linen and cotton, often with pastel shades or botanical prints, to navigate grassy lawns comfortably while looking chic.
