How to make maid of honor stand out...

You can have her with a different bouquet or a dress that is the same color but different style. Or same style, different color.

What Keatha said and You can also have her wear a long dress if the other girls wear short or vice versa

My MOH's bouquet will be wrapped in a different color than the rest of the bridesmaids

My MOH will have different jewelary ... and perhaps I'll allow her if she wants to put little spin things in her hair ... but I was adament all my girls were wearing the same dress, same shoes ... but remember you don't need to do anything in reality because most people are going to know that she is your MOH cause she'll be the one closest to you ...

my MOH its wearing a different dress from the rest of the girls!

If your dress has a colored sash, she can have the reverse.

Bigger bouquet.

Special hair piece or jewelry to make her stick out.

My bridesmaids are wearing a deep purple and my MOH will be wearing a metalic lighter shade of purple!!

My MOH will be wearing a red dress (our colors are red, black and ivory) with a black flower hair piece, and a bigger bouquet and BM's will be wearing black dresses with a red hair piece with smaller bouquets.

Mine is wearing a different dress and she will be very preggo by my wedding LOL but you can also try a sash in a different color if that goes with your BM dress :-)

Mine is having more to her bouquet or her bouquet will be different then the bridesmaids...

MOH is wearing a black dress with creme bouquet and the other girls will be wearing ivory and carrying a decorated starfish (kind of the same idea as a pomander) for each of the 4 corners of the Chuppah - she'll def stand apart!

My MOH will be having a different bouquet than the other BM's
