What Is a Semi-Formal Dress?

A semi-formal dress strikes the perfect balance between casual and formal attire. While black-tie events often call for a floor-length gown, semi-formal occasions give you more flexibility to wear a polished mini, knee-length, midi, or elegant maxi dress. The key is choosing a refined style that suits the occasion while reflecting your personal style.

Whether you're attending a wedding reception, engagement party, baby shower, graduation, or upscale dinner, a semi-formal dress offers the versatility to dress up or down with your favorite heels, jewelry, and accessories.
