Wearing boots with jeans is all the rage among the stylish set, but without a personal stylist at your beck and call, how can you be sure that on you, it's a fashion "do" and not a fashion "don't"? Help has arrived -- let Gretta be your personal stylist to guide you through the ins and outs of this hot fashion trend.

"The number one question I get asked about this look is: 'Is it age specific?'" says Gretta. "No! It's fit specific. You have to find your comfort and your fit. It's not easy to do. It's not about the rises -- how high or low the waist -- it's about the length."

There are three ways to wear boots with jeans. Gretta breaks down each one:

Tucking

Don't take a pair of wide-leg, flair jeans and try to scrunch them into a pair of long boots. You'll strangulate your leg! There's no way all that jean will fit into the boot so you'll get all the bunchy fabric at the knee.

Do wear tight, skinny jeans. They really lengthen the leg and fit well into a boot. If you're uncomfortable with skinny jeans, try wearing a longer top over them. Another great way to eliminate all that fabric from bunching up is by wearing a pair of cropped jeans. Wear your summertime faves or just cut off the bottoms of an old pair. No one will ever know and you'll look great!

Cuffing

Don't try to cuff a pair of wide-leg, baggy-fit trousers. They don't stay rolled and they cut off your leg.

Do go with a straighter cut, like a straight-leg jean. The cuff stays better and it's more flattering because it gives the illusion of a longer leg. As for the boots, stick to a classic style with a little heel; add that, you have a great look.

Hemming

Don't hem your jeans too short when you're wearing boots under your jeans -- it's all about the hem.

Do -- If you choose not to wear real skinny-leg jeans which go great for this look, make sure to wear them long. They can be boot-cut or straight-leg. You want to see the toe, so make sure you have anywhere from a four- to a half-inch hem.
