This gorgey City Style Sleeveless V-Neck Dress from New York and Company is the perfect go-to dress for any occasion. I love it paired with opaque black tights.
It's stretchy enough so you'll get a good fit, but cut very well to avoid unwanted lumps and bumps protruding all over the place. The dress is available in a bunch of colors and, yes, is only $8!!!
My advice? Buy it in every color you can! This is a classic dress that won't go out of style.
