What Should the Sister of the Groom Wear to the Wedding?

As a close family member, your dress should feel slightly elevated without competing with the bridal party. The key? Choose a style that’s appropriate for the venue and season, and that makes you feel confident from ceremony to reception.

Here are a few style guidelines to help you choose the perfect sister of the groom outfit:
Match the Dress Code: If the invite says black tie, a floor-length gown is ideal. For cocktail attire, go with a midi or knee-length dress.

  • Consider the Venue: Outdoor garden? A breezy floral works. Ballroom affair? Go structured and elegant.
  • Balance Bold and Subtle: Skip white, and avoid anything too attention-grabbing. Think sophisticated with a hint of personality.
  • Comfort Matters: Choose something you can move, mingle, and dance in.
  • Stick to the Season: Light fabrics for summer, rich tones and long sleeves for winter.
