This is perfect for a wedding! I am a wedding photographer and I have seen many brides use this and look just as flawless from when they put it on to the end of the night. You want to look your best for wedding photos so paying a little extra for the primer is a great way to do that :)
I think this make-up is worth the price. I use an array of products from them as well as their brushes and I wasn't a very "make-upy" person but this brand has changed my mind. I feel great about the money I have invested into.
Yes - I think it would be perfect for a wedding. I am getting married in August and will use it under my eye shadow. Hoping for perfect weather but if it is hot at all, I will need this product to keep my make-up looking fabulous. Congratulations!
