'It Girl' Cheat Sheet: Know Your Jessie J From Your Jesse Jo. Solve Cold Fusion. SAME THING.

Different people use the internet in different ways. Some use it to donate money to impoverished villages so the local community can install a watering pump in the center of town so you can access clean water without having to walk 7 miles or contract dysentery. Others use it as a tool to teach meaningful lessons to future generations of surgeons, lawyers, NASA engineers and still more teachers (god willing). We here at MTV Style use it for a great many fruitful things but mostly to find girls who are so pretty and so winsome with the best hair and bags and, lest we forget, their shoes rule really hard too. The information superhighway is STREWN with such gorgeous ladies (a nigh-ridiculous embarrassment of riches, really) to where it is sometimes difficult to keep them straight.

Two weeks ago (we know, we can't believe it's been so long EITHER), we introduced you to the full-lipped, blunt-banged, mind-bogglingly fetching Jessie J whose full-length album, Who You Are, comes out IN EXACTLY ONE WEEK. Then, as we skulked around in a non-creepy, totally-within-our-job-description, medium-to-high-grade stalking campaign of other pretties we want to collect know more about, which is around the time we ran into Jesse Jo. Such confuselment! Jesse Jo is a 19-year-old, mussed-hair moppet who has been a muse for the better part of her teens and photographed for Elle magazine by LEGENDS like Gilles Bensimon. Educate yourself. Know more and stay informed. Here's what to remember to keep them tidy in your brain boxes DESPITE both being equally stylish and pleasant to look at.

STRAIGHT-UP APPEARANCES:

First of all, they look MAD different. Jessie J hails from England and boasts a vampy, stylized appeal. She loves hella bold colors and often gives good smoky eye. Also, as mentioned before, has hard-core COMMITMENT BANGS.

Jesse Jo (right):

Jesse Jo LOOKS like she's from LA. Reliably disheveled looooooong hair with punk rock accessories. Gives good rich girl grime.

SHEER BLACK DELIVERED DIFFERENTLY:

So, as we mentioned before Jessie J is a bona fide recording artist (she went Platinum in the UK). Album. Out. In. Week. Cop. She has a definite performance element to her ensembles. Note the angular cutouts (she's a huge fan) and the monster platforms.

Jesse Jo (right):

Jesse Jo was born with strong ties to the music industry through her family. Like, um, CHER IS HER GODMOTHER. Real talk. And she has worked with Steve Jones of the Sex Pistols (no big deal) and Duff McKagan of Guns N' Roses for her own projects, which you can hear here. Cutoff Texas Tuxedo ramped up with the girly stockings. Again, very Los Angeles.

STATEMENT LEATHER JACKETS:

Jessie J (left):

Snug, cropped with a shearling trim but still fairly traditional. Huge hoops, Minnie Mouse ears (naturally) and a single forefinger ring. Check the manicure and the enormous smile. White seamless, studio shoot.

Jesse Jo (right):

Jesse on the other hand is typically shot candid by her bestie The Cobrasnake and looks slightly morose. Multiple rings. A Jeremy Scott bone-adorned leather jacket we would maim for.

LEOPARD PRINT SHOES VS. LEOPARD PRINT BACKPACK:

Both love animal-printed accessories and have the sartorial aplomb to combine it with a print. Jessie keeps it graphic and geometric.

Jesse keeps her leopard age-appropriate on a backpack in her Vans collabo lookbook.

IN TUNE WITH THEIR ROOTS:

Jessie J doesn't drink or smoke. Diagnosed with an irregular heartbeat as a kid, Jessie suffered a minor stroke at 18 and now keeps herself in clean condition by not pumping her facehole with poison. She also does "au naturel" by dressing in a surreal, full-on A Midsummer Night's Dream situation.

Jesse Jo (right):

Jesse Jo's parents are rock-and-roll accoutrement royalty--Laurie and Richard Stark. As in, the folks that founded Chrome Hearts. Jesse does nature by flinging herself into a pile of leafs dressed like a frickin' punk rock poster child.

BRIGHT METALLICS:

Jessie J (left):

Even when she's not onstage, Jessie J still looks vibrant. Her love of cutaways maintains as does her love of reflective surfaces and ornate, European-feeling, saturated prints. Super louche, super riche, super beautiful and put-together.

Jesse Jo (right):

Jesse Jo is similarly up-market in her choices (UM, CELLO JEREMY SCOTT CLOVEN HOOF BOOTS IN THE COLORWAY WE WANT BAD), but her outfit always looks deceptively casual. Short-shorts are par for the course, and the gnarly city dumpster seems as deliberately placed as a prop.

I MEAN, THEY'RE BOTH FREAKIN' ADORABLE, BUT YOU CAN SEE HOW THEY'RE WILDLY DIFFERENT NOW, RIGHT? THERE IS A QUIZ LATER:
