Destination wedding floral question

I agree with Hannah. There are some amazing vendors on Etsy that make bouquets and boutonnieres. I bought bouquets from Wedideas and SilkCoutoureFloral before I went shopping for my dress to get a feel of how colors would look with my outfit, and the other wedding party members. These shops both make boutonnieres as well, but SilkCoutureFloral made a magnetic boutonniere.

If you still want real flowers you can try the following:

You can always see if the town grocery store sells flowers and can make a small bouquet and boutonniere.

Or

Go to a flower shop the day before your wedding to pick up your bouquet and boutonniere. Make sure that you have plenty of space in your personal fridge to put the bouquet in a standing position, as well as the boutonniere. If you go the day of your wedding, make sure you have plenty of time to make the commute and still put your flowers in the fridge before you are ready to take your vows.
