Clothing is a very popular type of sexual enhancer. Obviously, there is the bedroom staple: sexy lingerie. And with the popularity of stores like Victoria's Secret in malls across the country, hot lingerie is available to women everywhere. But some couples prefer sensual clothing that is not quite so overtly sexual — things like silk robes, velvet pajamas, etc.
Couples can also enjoy clothing that fits with their particular fantasies or turn-ons: a French maid outfit, schoolgirl uniform, nurse uniform, etc.
If you are going through the trouble of dressing up in special clothing for your romantic encounter, be sure you have enough time to enjoy seeing each other wearing it (and, more importantly, slowly removing it). Clothing and other props aren't really intended for two-minute quickies, so save them for when you can enjoy a longer encounter.
