We got the outfits from American Apparel. The top is a leotard, it is completely backless and really cute. The skirt is also from American Apparel and is actually a tube top dress that we folded into a skirt. For extra props we had a bunch of dollar glow in the dark glow sticks, we had squirt guns (not shown in pictures), a bunch of silver jewelry, a lot of glitter everywhere and last the antennas were three dollars from a Halloween store. The outfits are really cute and easy to make.
