Squee! Spanx Is 60% Off On Zulily Today! I live for this day, when Spanx, which holds all my jiggly bits in so beautifully, goes on Zulily and updates my wardrobe for the following year. 60% off, baby! Take a look here... (PS: these offers end Thursday 4.21 at noon. If there’s something you like, buy it now. Sometimes they add stock, sometimes they don’t.) This is the biggest selection I’ve seen from Spanx- all the bras and undies, workout gear, jeans, leggings and swimsuits.
