Costume Accessories for Halloween: Red and Black Sequined Mask, Red Necklaces, Red and White Bangle Bracelets, Red Headband with Red Rosette
I bought the mask for $8 at the costume pop up store. The accessories were in my things. That's a good idea for saving money: get one piece that inspires you then "over-do-it" by doubling or tripling up on accessories or different kinds. That's how you go from regular outfit to costume, by amplifying what you've got.
Wear a sexy little black dress and get some fun stockings in red and youve got a cool masquerade costume. Done!
