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

Shopping for a mother of the groom outfit is exciting, but it can also be equally as daunting. Don't panic—we've got you! 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 articles that will 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, ideal length, and pair 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!
