When you can&#39;t get enough of your super Spanx pants but need something a little lighter for the everyday, look to <b>Spanx</b>&#39;s <b>Thinstincs slip</b>. The best base layer for a seamless shape, it&#39;s an updated take on the favourite, re-engineered with breathability and absorbency thanks to the impressive fine-gauge microfibre fabric. The addition of convertible straps makes it even more appealing - just layer it under demanding dresses for a confidence lift.
