What Should the Mother-of-the-Groom Wear to a Summer Wedding?

For summer weddings, mother-of-the-groom want to wear lightweight fabrics such as chiffon, silk, or linen, which are ideal for staying cool and comfortable. Opt for dresses or outfits that offer a bit of airflow without compromising on formality, especially if this summer wedding takes place outdoors or in a tropical destination. If the wedding dress code isn't black-tie or formal, you can opt for a tea-length or midi dress that keeps it elegant without compromising comfort in warmer temps.

It's also proper mother-of-the-groom dress etiquette to avoid white, cream or anything too close to the bride's dress color. Luckily, summer is the perfect time to lean into bold colors and fun prints. Vibrant florals are a big yes for this time of year, given that they're both joyful and sophisticated. If bold isn't your thing, intricate lace in a soft color can be incredibly flattering and never goes out of style. If you're daring, a sleek jumpsuit is en vogue and ideal for a chic, modern look that gives serious summer style.
