ASK most girls about the contents of their underwear drawer and they'll admit to having more than a few worn-out bras and grey, shapeless pants lurking in there.

We'd all like to say that it's actually full of super-sexy, matching lingerie that would make Dita Von Teese weep into her big, bubbly champagne glass.

But girls, as you know, the reality is more soft, comfy undies than sparkly, showgirl smalls.

So, why not make it your Valentine's Day mission to overhaul your underwear?

You never need an excuse to treat yourself to new lingerie, but if you're planning on a hot date with your man, those lived in, but zero sex-appeal bras and pants, just won't cut it.

Whether it's sweet, girly pastels or something a little more lacy and racy, the shops are filled with feminine, flirty styles he'll find impossible to resist.

Lingerie should have an uplifting effect, in more ways than one.

It should fit properly, giving you all the support you need, but it should make you feel fabulous too.

One of the keys to good dressing is wearing the right underwear. Think of it like a foundation to build upon - you may have splashed out on a gorgeous new dress or a slinky top, but wearing the wrong underwear will let you down bigtime.

If you've never been properly fitted for a bra, then do so - around 85% of women wear the wrong size.

Wearing the correct size can transform your body shape, so while the band around your body should be comfortable, it also has to be firm.

Remember, you're aiming for a smooth, streamlined silhouette.
