Coachella isn’t over yet but it’s already clear what the handbag of choice is at the music festival: none other than cross body handbags.

Here are a just a few of the many celebs who were (or are – today’s the last day) at the 2010 Coachella Music Festival, all sporting a different kind of cross body bag:

April 16, 2010 – Dita Von Teese attends the first day of Coachella

April 16, 2010 – The Hilton sisters Paris and Nicky at Coachella

April 17, 2010 – Katy Perry at the second day of the Coachella Music Festival

Even the people in the background in these pictures are sporting cross body bags!

It’s obvious why the cross body is so popular with concert goers: it’s comfortable to wear, it keeps your hands free to hold your drink, to clap, or to wave them in the air, and it keeps your stuff safely close against your body (very important especially in a crowded concert situation).

Even if you’re not going to Coachella, now is as good as any time to go shopping for a cross body bag. You’ll be ready to go if an occasion like Coachella comes up and it’s also good motivation to attend the festival next year (“But I already have an outfit to wear!”).

Here’s a picture of Ashley Olsen taken just recently.

Ashley Olsen (NYC)

She was spotted leaving Generra in a very casual outfit, save for the lovely pair of high heeled platform sandals on her feet. Both her sweater and shorts were oversized. Thanks to the leather jacket she tied around her waist, the outfit didn’t look as big. To cap off her outfit, she chose a black crossbody as companion for the day.

All in all, though I do not entirely approve of the whole oversized clothing, she carried the outfit pretty well. I think her shoes did the trick. It elevated her casual look and created some balance, negating a bit of the outfit’s “frumpiness”.

If you like this Ashley Olsen style, you can make it your own by borrowing your boyfriend’s sweater for that oversized look, but do scrunch up the sleeves to your elbows.

Also, be sure to wear a pair of good fitting shorts instead of Ashley’s loose ones.

I’ve been seeing a lot of celebrities carrying around these multi-strap, multifunction bags lately. One of them is sexy Latina star turned celebrity mom Jessica Alba, and her shoulder bag slash duffel bag slash cross body bag:

The picture above was taken just three days ago on April 1 when Jessica took her daughter Honor Marie out to lunch with her. Of course there’s no way a Hollywood star like Jessica Alba would be caught dead carrying a cheesy diaper bag, so she lugs all her baby necessities in a nondescript yet still stylish multifunction handbag:

I can see why mom (and even non-mom) celebrities like Jessica Alba increasingly prefer to use bags with lots of straps over single-strap bags. You obviously get more styles out of a single handbag as the straps let you carry it a number of different ways. Jessica Alba in these pictures for example, has to carry Honor Marie in her arms so she carries the bag on her shoulder to keep her hands free. She could use the longer strap and wear the bag as a cross body if she didn’t have a lot of stuff in it, and resort to using the shorter handles and carry it as a shoulder bag or as a tote as she puts more things in the bag.

I initially was averse to multi-strap bags because I feel like the extra straps will always get caught on something. But now, I think the uses that you can get out of this kind of bag overrules that strap problem. Besides, there are always bags that you can buy with detachable straps so you always have the option to leave them on or not.

Here are 3 multi-strap, multifunction bags that will get more bang for your buck:

Fossil Jackson Duffel, $198.00

The Sak Handbags Solana Duffel, $131.22

GUESS Rock Out Duffel, $90.37
