SheIn offers its SheIn Women's Long-Sleeve Applique-Panelled Lace Dress in White for $15.99 with free shipping. (Black is available for a buck more.) That's $3 under last week's mention, $16 off list, and the lowest total price we've seen. It's available in sizes XS to L.

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.
