What Should the Sister of the Groom Wear?

The sister of the groom holds a unique place in the wedding party, often balancing tradition with her own sense of style. While there are no strict rules, etiquette suggests choosing a dress that complements the wedding’s formality and colour palette without overshadowing the couple or bridal party.

Versatility is key, selecting a dress that can be worn again for other special occasions ensures your investment is both stylish and sustainable.

White Runway’s collection features re-wearable wedding guest dresses and formal dresses for special occasions, including plus-size sister of the groom dresses, so every woman can find a flattering fit.

How to Choose the Right Dress for the Wedding

Considering the Wedding Theme and Venue

The setting and style of the wedding should guide your dress choice. For a beach or garden ceremony, lighter fabrics and softer colours work beautifully. For a black-tie affair, opt for structured silhouettes and richer tones.

Coordinating with the Bridal Party

While you don’t need to match the bridesmaids exactly, it’s thoughtful to choose a dress that works with the overall colour scheme. This creates a cohesive look in photos and shows respect for the couple’s vision.

Flattering Your Figure and Personal Style

Select a silhouette and neckline that highlight your best features and make you feel comfortable. White Runway offers inclusive sizing and a variety of styles, so every sister of the groom can find a dress that feels uniquely hers.

 

Accessorising Your Look

Statement Jewellery and Hairpieces

Elevate your outfit with carefully chosen accessories:

  • Earrings or a necklace: Add sparkle without overwhelming your dress.
  • Hairpieces: A chic headband or decorative pins can complete your look.

Shoes, Clutches, and Outerwear

  • Shoes: Choose comfortable yet stylish heels or flats to suit the venue.
  • Clutch: A small, elegant bag keeps essentials close at hand.
  • Outerwear: A tailored shawl or wrap is perfect for cooler evenings.

Thoughtful accessories ensure your ensemble is polished from head to toe.

Sister of the Groom Dress: What Should She Wear?

Frequently Asked Questions

Can the sister of the groom wear white? +

Traditionally, white is reserved for the bride. It's best to avoid white or ivory unless the couple specifically requests it, to keep the spotlight on the bride.

Should the sister of the groom match the bridesmaids? +

There's no requirement to match the bridesmaids, but coordinating with the wedding's colour palette is a thoughtful gesture. This helps create a harmonious look in group photos.

How to stand out without overshadowing the couple +

Opt for elegant details and a flattering fit, but avoid overly dramatic styles or colours that might draw attention away from the couple. Subtle embellishments and sophisticated accessories can help you shine in your own right.

What are the best styles for sister of the groom dresses? +

The best styles for sister of the groom dresses can vary based on the wedding theme and season. Popular choices include elegant floral maxi dresses for spring or summer weddings, and long formal gowns or midi dresses for autumn and winter events. Consider a cocktail dress for a more relaxed celebration or a formal evening dress if the wedding is black-tie. Styles like A-line and mermaid silhouettes are flattering on many body types, making them great options.

Can the sister of the groom wear a dress that matches the bride's dress? +

While it's generally best for the sister of the groom to choose a dress that complements rather than matches the bride's dress, coordinating colours or styles can be a beautiful way to showcase family ties. For instance, if the bride wears a satin dress, the groom's sister might opt for a similar fabric or colour palette in her outfit, like a v-neck midi dress or a floral one shoulder maxi dress.

What is the appropriate dress code for a sister of the bride or groom at a wedding? +

The appropriate dress code for a sister of the groom depends on the wedding's formality. For a black-tie event, a floor-length gown or formal evening dress is ideal. For a beach wedding, a flowy maxi dress or a chic cocktail dress may be more suitable. Always check with the bride and groom to ensure your outfit aligns with their vision for the wedding party.

Are there specific colours the sister of the bride or groom should avoid? +

It's typically advisable for the sister of the bride or groom to avoid wearing white or ivory, as these colours are traditionally reserved for the bride. Additionally, consider avoiding colours that may clash with the bridal party or family attire. Instead, opt for colours that enhance the wedding theme, such as soft pastels for a spring wedding or rich jewel tones for a winter celebration.

Can plus size find stylish dresses? +

Absolutely! There are many stylish options for plus size. At White Runway we offer inclusive sizing and styles that flatter your figure, such as A-line dresses or gowns with wrap and flowy silhouettes. Dresses with pockets or those featuring a deep v-neck can also add a modern touch to your look.

What type of accessories should the sister of the groom consider? +

Accessories can elevate the outfit significantly. Consider elegant jewelry that complements the neckline of your dress, such as a statement necklace for a halter neck or simple earrings for a v-neck dress. A stylish clutch and appropriate footwear, like strappy heels or chic flats, can complete the look while ensuring comfort throughout the day.
