Groom's First Look

I can't decide when to do the groom's first look...I know the tradition is for the groom to see you for the first time at the ceremony, but it's become a lot more common to do the first look before the ceremony. When weighing the pros and cons of both, I keep going back and forth. As for my fiancé, he doesn't have a preference and wants me to do it however I want. I would so appreciate to hear other brides' decisions on the first look and their opinions on why they chose to do it that way. Thanks in advance!!
