Wedding Brooches - Help!

so i need to get a pin to help hold up the sashes once the dress is bustled.

i've seensome brooches online, but i don't know if these pins have to be larger to hold up the sash or if it can be a regular pin - obviously it would have to be larger one and not a small one - but you ladies get my drift.

is there a specific tyoe of brooch i should be looking for?

i want something all blinged out with crystals!

If you are concered with size - i would be careful buying it online. Maybe hit up some flea markets (now its that time of year) or even antique shops and im sure you can find something really beautiful and then can see how big it is.

Since its holding up a sash - i would think it would need to be a little larger just to grip the fabric correctly.
