A black jumpsuit is easy as can be, and this one is just as stylish. 

Thin black jumpsuit with zipper up the center. Attached and somewhat adjustable belt cinches in the waist. Two straps on either side to create optional necklines, ex. the keyhole pictured. Jumpsuit is fitted with small white polka dots throughout and a small flare in the legs.

Wear this with a wedge for a fun, springtime look.

This item is sold from an excellent, highly rated vintage boutique in Burbank, CA.
