When it seems like the hot and humid days of summer just won't end, stocking up on easy, throw-on-and-go dresses is really in your best interest. Find a style that also happens to be crazy affordable and I say get one in every color!
That's why I just had to share this amazingly simple, yet must-have tank dress from Old Navy. It's currently on sale for just $12, but get this--it has over 750 positive reviews! Women can't get enough of this dress! There's also a short sleeve version that's super popular, so click through the slideshow to shop them both.
