Weddings are more than just a celebration of love—they’re a full-on family affair. And while the spotlight often falls on the couple and the mother of the bride, let’s not forget the other equally important mama in the room: the mother of the groom. If you’re preparing for your son’s big day, you deserve to feel elegant, empowered, and absolutely radiant in plus size mother of the groom dresses that celebrates you and your shape.
As part of our annual Plus Size Bridal Week—your ultimate guide to everything plus size and wedding—we’re spotlighting the style, fit, and fashion tips every mother of the groom should know. From inclusive designers to curve-celebrating silhouettes, this guide is here to help you shine just as brightly as the occasion itself.
Finding the perfect plus size mother of the groom dresses is about more than just style—it’s about confidence, comfort, and honoring your personal flair. Whether the wedding is a black-tie affair or a breezy beach ceremony, we’ve gathered tips, style advice, and stunning picks to help you shine.
The Mother of the Groom: Your Role & Your Moment
Traditionally, the mother of the groom has played a supportive, behind-the-scenes role—but today, she’s very much a part of the spotlight. From the rehearsal dinner to the reception, your look should reflect your importance in the wedding journey.
A few things to keep in mind as the mother of the groom:
- Coordinate (but don’t match) with the mother of the bride. David’s Bridal shares that “traditional courtesy advises that the MOB gets to pick her dress first, so you can coordinate plans with her, and then let your taste lead you through our collection of elegant dresses and two-piece ensembles.”
- Respect the couple’s vision and wedding theme.
- Consider timing—start shopping at least 3–6 months before the wedding.
- Discuss dress codes and color palettes with the couple or wedding planner.
And most importantly? This is your moment too—own it in a dress that makes you feel like your most fabulous self.

When dressing for such a milestone moment, it’s all about fit, fabric, and flair. Here’s how to narrow down the perfect look:
1. Go for a Fit that Celebrates Your Shape
Look for silhouettes that highlight your curves with comfort and confidence:
- A-line gowns offer graceful movement and timeless elegance.
- Empire waists create length through the torso and give a regal finish.
- Wrap dresses enhance your natural shape and provide flexible ease.
2. Choose Luxe, Drapey Fabrics
Fabrics matter—especially when it comes to comfort and elegance.
- Chiffons, jerseys, stretch lace, and tulle create beautiful movement.
- Velvet or crepe adds structure without feeling heavy, great for evening affairs.
3. Don’t Shy Away from Color
Lovella Bridal shares great tips regarding color choices and how to make this work with the Bride and Groom. If the color options do not work, Lovella Bridal advises “be sure to give this feedback to your son or daughter and see if there is another complimentary color that could work with their color scheme and also allow you to feel better in your attire and still flow with the overall look.”
4. Think Beyond the Dress
Accessories are where you can truly make it yours. Statement earrings, a sleek clutch, or bold shoes bring your full look together and add your signature touch.
5. Prioritize Comfort & Confidence
You want to feel amazing from the ceremony to the dance floor. Look for styles that move with you and consider supportive undergarments if that enhances your comfort.
