Ultimate Jeans Challenge

Expert tip: A good idea for shorter women trying to work skinny jeans: Throw on a heel. "A pair of heels is going to give you some length and height," Shatonia says. "It's also going to help improve your posture which makes you look taller and slimmer."

"These jeans are perfect for Ivana because they give her a true hourglass look," Shatonia says. "They're like a girdle, but with spandex! They suck her in and slim her waistline, give her lift in the back, and just give her a firmer look all over."

This dark wash also works for Ivana because it makes her look longer and leaner, and the boot cut leg gives her shape.

"The darker wash of these jeans gives Michelle a very lean silhouette," Shatonia says, "and we gave her a high-waisted style to bring some shape to a high torso without a ton of curves."

These jeans cover her problem areas with a slightly stretchy fabric, and they have big, wide, flat pockets in the back "to give her the illusion of a butt," Shatonia says.

Shatonia recommends a low-rise jean for girls who have hourglass figures like Michelle because they lay flatter and sit properly on the hip.

"These won't be gaping at the waist like they would if they were a higher rise," she says. "We're also balancing out her generous curves with the boot cut leg."

Because Heather is very petite and slim, she can wear any type of wash or jean shape, as long as she finds the perfect length.

"If you're anywhere from a size 0 to a 6 or 8, I recommend going to the petite section to find jeans," Shatonia says. "Then, go home and take an iron and crease the front of your jeans to give yourself even more of the illusion of height."

1. There's bunching, wrinkles, or sagging in the crotch area. "You shouldn't have excess material in your crotch," Shatonia says. "Your jeans should be able to come all the way up and lie flat in that area. If not, your jeans may be too big, or your inseam may be too long." The solution? A lower-rise jean.

2. Your jeans are pulling and creasing in the crotch. "This means your jeans are too tight," Shatonia says. "You may want to try a jean with more stretch. Don't be afraid to go up in size, either — remember, your main goal is comfort!"

3. There's a large gap in the back of your jeans. "If you can fit your fist in the back of your jeans, but they fit fine everywhere else, you need to opt for a lower-rise jean," says Shatonia. "Try a mid-rise; if there's still a little space, go for a low-rise. When changing rises, make sure the jeans fit comfortably, and be sure your underwear is not visible. Sit down in them to make sure you aren't revealing too much. If a low-rise is too revealing but there's just a little space in the mid-rise, you can always wear a belt or have them altered."

4. Your jeans are creating a "muffin-top." "There are a few reasons this may be happening," Shatonia says. "One reason could be that your jeans are too tight. Again, don't be afraid to go up in size — it's only a number! You want to be comfortable and look good. Another reason could be that you need a higher rise — your jeans should lie flat on your hips and waistline. When a pair of jeans is too tight or low, they can create that unwanted spillage, or muffin-top, on anyone, regardless of size."

5. Your jeans are either hitting the top of your ankle or they're dragging, even when you're in heels. "The length of your leans is a big factor in fit," Shatonia says. "If your jeans only come to the top of your ankle, opt for a longer jean. Some designers indicate length in numbers, but some use S (short/petite), R (regular, for women of average height), or L (long, for woman who are over 5'6). Another problem occurs if your jeans have a lot of bunching at the bottom and are dragging on the ground. If this is the case, you need to opt for a petite style. If this is your issue, I suggest shopping at department stores; not many boutiques offer petite sizes, while most major department stores have a whole department for petite women."
