I put together a black widow costume - mostly from ebay. black spiderweb dress (which is pretty sheer so I wore a braslip under it) -spiderweb tights, black bob wig & made myself a pill box hat with a veil over it. I wore diamante spider brooches, bracelet, earings & choker (& fake fingernails with spiders on them. a couple of spiders sewn on to the hat & dress but trailing from a thread so you can see movent. not seen anyone else in this costume & I got a lot of good comments about it
