Let's say you haven't been dating for very long, and you don't want to come off like a commitment-obsessed psycho by going all out on a super-formal Valentines Day date. So you're keeping it casual. Sounds easy, right?

Sort of. While, chances are, you dress down for most nights grabbing dinner, catching a movie, or just vegging out on the couch, this is still a special occasion -- even if you're both pretending it's not. Make sure your date knows you care by dressing it up a notch. Don't go nuts -- showing up in black tie attire (or a formal gown, or whatever) is likely to make your relatively unfamiliar partner feel really uncomfortable.

Ladies:

• A little extra attention on the accessories goes a long way. Try a nicer necklace, or even some glitzy earrings.
• Remember, you're going for a look that's slightly spruced up compared to how you normally dress. So if your everyday style is a ratty t-shirt and sweatpants (God forbid), a pair of jeans and halfway decent top will do the trick.

Guys:

• Unless you're particularly fashion-forward, look for little ways to show you thought about your appearance before the big (albeit casual) date. No hats, no holes, no beer logos.
• Shoes are the key -- they can be the difference between slob and sloppy chic. Try a stylish slip-on -- it's inexpensive, effective, and laid back enough for jeans and an untucked shirt.

So give it a shot. With a small amount of forethought, you can help make sure this isn't the last Valentines Day the two of you spend together.
