Answer: Heck YES (to the power of 10)!
I would 100% recommend getting a bouquet/boutonniere combo for your elopement. It really ups the feel of the elopement and can help brides feel less anxious about what to do with their hands. You can always put the bouquet down so it’s not in all the pictures ?
The Haku lei (flower crown) is also a gorgeous addition that can make your Hawaiian elopement that much more tropical. These items are generally readily available at certain grocery stores and can be purchased for less than $100. There are several people that specialize in Haku Leis for brides, and those tend to go up in price depending on the flower arrangements.
Whatever kind of flower you choose, it will be a beautiful addition to your day.
