I only like Halloween for the dog and toddler costumes, and this one I am not even sure you can call a costume!  This  a formal dress in black "satin" with a netted under-skirt and slip and a hot pink bow/belt  Looks like a prom or bridesmaid dress, So if your dog is invited to participate in one of these events, here you go!  It closes with velcro underneath.  And believe it or not was designed by the New York designor, Izaac Mizrahi!  So you can say your dog is wearing a designer gown!   I have other costumes in my store if you are interested.  Happy Halloween!
