Purchase synthetic flowers instead of the natural ones. Synthetic flowers may cost a bit more when you buy them in bulk, but they could save your money as they last longer than the natural ones. Here is how it will be worthy to buy the synthetic ones; when you buy the natural flowers for flower girls, bridesmaids, as well as for yourself, they tend to whither rather quickly, more so in case of indoor weddings. As a result, you may end up buying more fresh flowers. One more advantage of buying synthetic flowers is, you can chose any petal color, any bloom shape as per your preferences and thus giving you more freedom in planning the decoration at your wedding.
Whichever way you decide to go with your flowers, a lovely idea is to try and tie your whole theme together so if you're going for roses, then have a rose design featured somewhere within your headdress. Look out for a company who can work with you and your designs and most importantly your budget to create that one_off, bespoke creation just for you.
