If you still don't know how to choose bridesmaid dresses for your wedding, how to make sure your bridesmaids look cohesive if they're wearing different dresses. Let me tell you about it.
Don't give them too many choices: This actually goes for all bridesmaid dresses, not just mixed-and-matched ones. Make a separate appointment without your bridesmaids to decide their options in advance. Pre-select the dresses, necklines, and colors that you like. Then, let them choose their favorite. It will save you a lot of confusion at the ordering appointment when you are all together.
Shades of color: Different colored dresses are very popular right now. But it can be difficult to select ones that look good together since you're limited to the colors the designer offers. Also, the small swatches on a card often look very different when they are made up in a gown. The easiest way to visualize how they will look together is to check out the full-size samples in daylight, and switch out different options until you are happy with the combo.
