Blue has been a popular bridesmaid dress color choice for a while – but with so many shades to choose from, how do you decide? Of course, you could have your ‘maids each pick a dress in a different shade of blue to create a pretty palette, but if you just want to pick one shade, think about your venue. Lighter blue shades look best in the warmer months, at less formal weddings in outdoor settings like the beach or garden. Darker shades are ideal in colder months (though navy looks great year-round!) for more formal weddings at country clubs or ballrooms.
