Keep It Simple
If you look at a lot of formal dresses intended for older women, they can be very fussy. There are often lots of beads, feathers, folds and taffeta. Presumably, the intention is to flatter all the bits you might not be so confident about. But for a lot of women, these details draw a bit too much attention to them. You don't want everyone to be looking at you over the bride because your outfit stands out so much. For a different idea, you could try going for something more simple. Avoid any of the frills and fussy details, and instead, go for a something long and flowing. Go for simple but sophisticated, not dazzling and sparkly.
Not every woman wants to wear a dress to all formal occasions. There are other options if you wish to consider something else. Some of the best mother of the bride plus size outfits can be more flattering if they're suits or two-piece outfits instead. You could wear a skirt and top, instead of a dress, which can feel more comfortable as well as be looking great. If you don't want to wear a dress at all, switch it out for some trousers instead. A smart suit can be an attractive option, although you don't have to wear a jacket. You could choose a cardigan to keep you warm instead, or a soft shawl.
Be Inspired by the Wedding
The wedding itself can give you inspiration for what to wear. For starters, you don't want to dress incredibly formally if it's a bit laid-back. The bride will probably give you some hints about what to wear and what the venue will be like. You can let these things inspire you to pick an appropriate outfit. For example, you might tie your outfit into the wedding colours or go along with the theme.
Stylish But Comfortable Shoes
Don't forget to pick some beautiful shoes to go along with your outfit. Of course, you don't want to be uncomfortable all day, though. Don't suffer through wearing six-inch heels just because they look good. Find a pair that goes with your outfit, look stylish and feel comfortable. That's easier said than done, but you should be able to find something you love.
Choosing a mother of the bride outfit can be a great chance to bond with your daughter. Go shopping with her or show her your choices to discuss it together.
