plus size mother of the groom dress

Although it's the happy couple's big day, as the mother of the groom, you deserve to find an outfit that not only showcases your personal style but also celebrates your figure. Finding a plus-size dress that feels and looks amazing can be a challenge, but your search ends here. From black-tie gowns to knee-length cocktail dresses, there are numerous dress styles that will work for any occasion, venue, and wedding aesthetic.

When shopping for a plus-size mother-of-the-groom outfit, you'll first want to consider the silhouette. A-line and sheath silhouettes are always flattering options for any body type, but feel free to experiment with whatever speaks to you. Once you've nailed the silhouette, you can start narrowing your choices down by matching your dress to the wedding colors and theme, season, and dress code. Floor-length gowns are a must for formal events, but you can opt for mini and midi dresses for more casual occasions with a cocktail wedding dress code.

To help you find the perfect dress for your son's big day, we've researched various options from trusted retailers with these features in mind. If you're in the market for something utterly elegant, the BHLDN Serephina Crepe Maxi Dress will stun at any black-tie affair. For a pop of color and texture, we love the Mac Duggal Ruffle Wrap Effect Dress (Plus) and the Adriana Papell Plus Size Hand-Beaded Midi Dress.

When choosing your dress color, make sure it doesn't match the bride's wedding dress or groom's suit or tuxedo. If you're unsure about the color, run it by the bride and groom first.

What to Look for in a Plus-Size Mother-of-the-Groom Dress

It goes without saying that you'll want to look and feel your best on your son's big day, so finding an outfit that's stylish and fits you perfectly is of the utmost importance. Before you start your search, it's helpful to identify what silhouettes work best for your body type and what assets you're looking to show off. We've got tons of resources to guide you along the way when it comes to styling your body type and finding dresses to buy.

Then, you can narrow down your options by taking cues from the wedding's theme, color palette, and dress code. Allow for plenty of time prior to the wedding to research and experiment with different ensembles before it's time to make a final decision. After you've locked down your look, make sure to slip it on one or two times leading up to the big day to ensure a seamless fit and ideal length, then pair it with the perfect accessories. Take your gown to a seamstress if the dress you purchased needs alterations—and don't forget to hang and steam your gown the day before!

FAQ
  • What colors should a mother of the groom avoid wearing?

    Unless specifically approved by the couple, a good rule of thumb is to avoid wearing white or any hue that might resemble the bride’s wedding dress or groom’s suit or tuxedo. Also, if you're considering a super-bold color or loud print, it may be best to run it by the bride and groom first.

    Light and airy colors, as well as fun floral prints, are always great for spring and summer ceremonies. Winter weddings and formal affairs often call for darker, jewel-toned hues like navy blue, black, or burgundy. So these are good considerations to keep in mind when deciding on the color of your mother of the groom ensemble.

  • Do I have to run my outfit by the couple?

    While the couple will surely want you to feel your best in your mother-of-the-groom outfit, having a conversation with the couple beforehand can help. This can help set expectations and also narrow down your options when searching for your perfect dress for the big day.

  • What is the most flattering dress silhouette for a plus-size mother of the groom?

    Some of the most flattering dress silhouettes for a plus-size mother of the groom are A-line, mermaid, and sheath. With that being said, mothers of the groom should always feel empowered to experiment with all different types of silhouettes.
