When to wear/take off a flower crown?

That is up to you and how long you want to wear it. Every bride does it different. Maybe for the reception>

You could totally do either way! I would maybe wear your veil for the ceremony and the flower crown for the reception or wear both and then no veil for the reception. I’ve also seen where the flowers aren’t necessarily is a crown but like on the veil comb. It depends how you want your hair and photos! But I would wear one and then the other.

I've always seen pictures of them as separate pieces. The veil attached to a comb under the flowers that can be removed anytime. Talk to your florist for other ideas.

You can wear the flower crown during reception

I feel like they're more part of the hairstyle.

Thanks everyone!
