The last time I was in Jamaica I "tested" my newly cut "straight" bangs. I am African-American and my hair is relaxed and in December I was in Jamaica I wore my freshly blown out hair with big barrel curls down to my shoulders and POOF it went right up.
I cut bangs to see how they would do for the wedding based on my glam style. In April my hair did just fine - I carried a flat iron with me and it stayed straight with a light morning touch up.
When I met with Sonia the wedding coordinator at Tensing Pen I showed her my style - also with FAB bangs. She loved it (as do I) and was certain that the stylist could make it happen for the wedding. The stylist is about $100.
I would choose what you feel comfortable with and work with the stylist to make it happen. I am prepared to start on my hair first thing the day of the wedding to make sure we have enough time.
