Preparing to buy lingerie is the most pleasurable homework you'll ever do. Basically, it means watching your wife or girlfriend as she parades around the bedroom getting dressed or undressed. She what she's comfortable with. Does she like strapless bras or ones with straps? Underwire or smooth cups? Full coverage or demi bras? Panties or thongs? And if she doesn't wear the latter, why? Does butt floss make her uncomfortable? Or are thongs just not something that fits in with her everyday wardrobe? Would she be willing to wear one if it weren't something she'd have on from morning till night, if she'd be wearing it for a more intimate, relaxed and shorter period of time?
