Looking to have a sexy night in? Perhaps you're just looking for an upgrade when it comes to boudoir wear. If your relationship is getting stale and needs spicing up, then a change in PJs might be in order. We're not talking about investing in XXX-worthy teddies or crotchless panties, necessarily. One of the sexiest things you can put on display in bed is self-confidence.  So if you don't feel attractive and confident in a conventionally "sexy" set of lingerie, then pass on it. We know you don't feel attractive in those old, ratty sweats, so don't wear those, either. Being comfortable and confident in your own skin is the way to appeal to your partner.
