Drop veils are the sheerest veils offered. They drop over your head. There is no comb and no gathering at all. They are attached with hat pin. The veil is draped over the head and if you had a head piece the veil is draped over that as well. Then you take the hat pin and you just weed it in and out between the hair and the veil several times. Now after the ceremony all you have to do is remove the pin and the veil is removed without ruining the hair. To measure for the drop veils take a piece of string and cut it to the length of the veil. Hold one end in front and let it drape over head. Take your hairstyle into account as well. You can control how much you want in front and how much in back.
