I'm delighted to hear that you're thinking about something special to wear. Guys vary greatly in what they like when it comes to lingerie. Some like very classy, some very suggestive, some (like me, for better or worse) love trashy little nothings. If you don't know, get a Frederick's catalog and maybe one from Victoria's Secret and ask him to indicate the ones he likes the most. You don't have to tell him exactly why. No guy with a pulse needs any encouragement to review a lingerie catalog. Then go find something like he showed you that you feel good about yourself wearing. It's just as important that you feel sexy in it as it is that he likes it. If the balance is right, you'll only have it on for a very few minutes. One final hint: the sexiest article of clothing in the world, IMHO, are red patent stiletto pumps. Sexyshoes,com is a great place to find really sexy footwear. In case you need a testimonial, Mae West once said, "A woman in red stiletto pumps can make a man bark." Woof woof!
My husband likes lacy lingerie that you can see through but still kind of preserves some mystery in the front and spaghetti string in the back. Red is always fun. I also have a couple of outfits he likes, school girl and nurse. Good luck.
