Keep in mind that your hair and face shape should play a big role in what flowers you choose to adorn your floral crown with. Don't let huge, full-blooms overpower a small frame or limp hair. On the other side of the wedding stress coin, always remember to not use tiny buds if you have got the wrong style wedding hair for the look.
Are you going to go big, poofed out hair? Will you do a classic bun, pulled high off your neck?
All these decisions lead you towards the right floral.
You can go with a small clustering of mini red blooms for a smaller, more understated hair piece. For the more statement kind of tiara pick out half a dozen large diameter single stems to arrange around the forward face of your floral tiara.
If your ideal flower headpiece is more of a headband, think about using small blossoms with no filler to create a soft, vibrant headband of flowers that will match your wedding's colors and tone.
For high contrast bursts of color this is also a super fun choice. If you want a dash of hot pink on your big day a tiara of tightly wound pink flowers can be perfect without being too youthful.
If you want to do all creams, adding in a flower with bright, sweet green stems can add just a tiny zip of contrast.
Thoroughly soak the already cut short steams of your crown's flowers the day before. The day of use mini water flasks of lightweight plastic to keep a few extra big blooms fresh looking all day.
