SheIn offers its SheIn Women's Round Neck Pleated Dress in Grey for $18.99 with free shipping. That's $14 off list and the lowest total price we could find, although we saw it for $2 less last April. It's available in select sizes from S to XL.

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.
