No matter how tastefully erotic the lingerie, men typically only focus on its impending absence -- making it impossible to see it on a rack, then visualize what it'll look like on a rack. Give negligee a trial run, with Knicker Picker.
KP's an "online dressing room" that allows you to dress actual models in an array of bras and panties, thereby gleaning how the garment'll look on your significant someone without spoiling the surprise, or making your mom try it on. First, pick one of three models (small/average/big-boned), then pick from the undergarment-loaded scrollbar -- styles by the likes of Passionata, Mademoiselle, and Calvin Klein (Sears turned 'em down when they insisted the models also shill rototillers). Your model'll then stroll out rocking your selections and, at your request, turn around or walk forward, eliciting either a giddy smile or a look that might be petulant, or plain angry -- figuring out which is reason enough to keep replaying the loop.
When you're done ogling the options, just click to buy -- so later that week, you can spend 5 seconds admiring how good your choices look on your girl, before old habits kick in and you decide they'd really look better on the floor.
