But buying a stepmother-of-the-bride or stepmother-of-the-groom dress may not seem quite as straightforward as shopping for your typical wedding guest attire.

What Should the Stepmother of the Bride or Groom Wear?

Communication is key when it comes to choosing an outfit for your stepchild's wedding. If you played a parental role in their upbringing, the bride- or groom-to-be might be happy for you to wear a similar outfit to the MOB or MOG. That said, if your stepchild's mom is also an important figure in their life, it's important to respect her wishes too. If wearing a similar outfit to the mother of the bride or groom causes upset or tension, it might be best to tone down your attire as stepmom and wear something on par with other loved ones attending the nuptials instead. Dress etiquette for the stepmother of the groom or bride isn't set in stone. Ultimately, it's something each family should figure out for themselves.

How to Choose a Dress as Stepmother of the Bride or Groom

Whether or not you're following traditional MOB or MOG dress etiquette, we've got a few tips to help you choose the perfect wedding guest attire. There are three essential elements to take into account: the venue, the season and the formality. Let the setting and season inspire what kind of colors, prints and silhouettes you consider. For example, a garden wedding in the spring or summer invites romantic, floral styles in dusty shades of pink and blue. On the flipside, a winter wedding at a castle or estate calls for floor-length formal styles in rich hues such as emerald and burgundy. The venue will also give a clue as to how formal the wedding will be, but the couple may provide a specific dress code on their invitations or wedding website.

Once you've got a few options in mind, the next thing to think about is comfort. Your stepchild and their new spouse will want you to enjoy every moment of their wedding day (which gets a lot more difficult if you've got a zipper digging into your side or an itchy neckline). If you're ordering an outfit online, leave enough time to try it on and return if necessary. It's worth taking the time to find something comfortable so you can fully immerse yourself in the occasion.
