Hair Flowers- Store?

I'm going to a wedding in a few weeks, and FH expressed his desire for me to wear my hair up for a change. I have the tendency to look very severe with my hair up, so I want to add a flower or something. I'm on the fence with wearing a blue dress or a coral dress. I found a beautiful pink/coral set from ButterflyEnchantress on etsy that's not too much money, but I'm concerned I won't get it in time.

Does anyone know of a store I could go to (preferably in Suffolk) that sells hair flowers, similar to those with the crystal centers? Or, the girls that did order through that vendor, what was the total turn around time after shipping? TIA!!
