SheIn offers its SheIn Women's Puff Sleeve Slim Dress in Navy for $18.32 with free shipping. That's $14 off and the lowest total price we could find, although we saw it for $2 less during Black Friday week. It's available in sizes S to XXL.

Note: Uncheck "Add Shipping Insurance to your order" during checkout to remove the 99-cent fee. This item ships from mainland China and should arrive in three to four weeks.
