Powdered Sunscreen...yeah it's a thing!  Those outdoor weddings can be brutal on a bridal party's skin.  With pictures and the actual ceremony/reception all outdoors it's no wonder so many people get sunburned at weddings (on their shoulders and especially face if their makeup isn't SPF or they missed a spot).  To make sure your bridal party isn't miserable after a few hours in the sun and your photographer will thank you for not having him shoot lobsters by the end of the day :).  I've used it on myself and my brides for a few years now...LOVE IT!  Check it out's SPF50, waterproof and has a built in brush so it's easy to apply (it's not greasy like other sunscreens so it won't ruin photos or dresses).
