Frederick's of Hollywood
takes 20% to 30% off
most items sitewide. (Discount is taken in cart.) Plus get free shipping
on all orders via coupon code "SHIPFREE". That beats our February mention, when we saw 25% off with free shipping, and the best sitewide discount we've seen from Frederick's of Hollywood so far this year.
A best bet is its Frederick's of Hollywood Women's Lea Babydoll in nine colors (Coral pictured) for $24 before the in-cart discount, $16.80 after. With free shipping via the above coupon, that's $7 off and the lowest total price we could find. It's available in sizes S to XL, although not in all size/color combinations.
