Maggie, I have zero to little corsage experience.
I have a wrist corsage, navy blue ribbons on a silvery bracelet, and that part is working.
White roses seem the obvious choice, for longevity.
Can you suggest anything better? The girl's dress is deep navy, amost black.
I would love fragrance, but gardenias are out, because expensive and temperamental. I don't want want to fuck up a gardenia, and don't know what will survive well outside of water.
I'm limited to grocery store flowers, because I'm too lazy to drive 25 miles to the warehouse and don't need to buy in bulk. Have wire, tape, all that.
