Birdey Grey Christina Convertible Dress 

From the designer: Christina Convertible Dress comes with 2 extra long streamers attached at the waist (plus an extra detachable streamer & sew-on spaghetti straps) so you can let your bridesmaids choose how they want to wear it—strapless, halter, Grecian, cap-sleeve—while keeping the overall look of the bridal party cohesive. *Just a head's up: Christina runs small... if you float between sizes, please order up.
