Shopping for perfect fitting jeans doesn't have to be an exercise in exhaustion. Know the styles and brands that fit and flatter, and you'll look thinner, taller, trimmer.

Pear Shape: Before

"I'm frustrated by my pear shape — if jeans are roomy enough for my hips, the waist is too big"

Before: Too tight, too tapered — and tucked into chunky, clunky boots.

After:

Both the body-friendly fit and the finish of these tailored denim trousers ($132, Cj by Cookie Johnson) cater to Aimee's curves: The contoured cut (it's higher in back) won't gape at the waist, and the wider leg balances her hips. Bonus: The tone-on-tone stitching creates a long, lean line.

Flat Butt: Before

"My behind is as flat as a board! I want a cute booty"

Before: High-waisted mistake — saggy, baggy, and barely even blue.

After:

Trim and tush-flaunting, theseindigo jeans($70, Gap) boost Carol's booty with strategically placed pockets — they sit a little higher than normal, so her rear seems rounder. Also bringing up the rear: a double row of decorative, rump-plumping stitching on the back pockets.

Wide Hips: Before

"I end up with low-slung styles to fit my hips — and I'm sick of flashing cheek cleavage"

Before: Frumpy, faded, and fighting her flirty figure.

After:

Thanks to their arrow-straight shape, these crisp classics ($54, Lee) skim Rachel's curves. Subtly whittled and higher at the waist, they won't bare her backside.

Thick Thighs: Before

"I'm always battling my thick thighs. Any jeans that are fuller in the leg?"

Before: Sausage-casing snug, with lots of unsightly creasing at the crotch.

After:

Constructed for curve management, these stretchy flaw-fixers ($120, NYDJ) accommodate Alex's extra inches. Adding to the slenderizing effect: the deep, dark rinse.

Curvy Caboose: Before

"I have a curvy caboose, and I try to camouflage it by wearing a looser, larger size"

Before: Beware of pockets spaced this far apart — they'll broaden any butt.
 

After:

The lower-positioned pockets on these derriere downsizers ($88, White House Black Market) decrease Teresa's fuller fanny. A midrise flare cut minimizes it even more.

Mushy Middle : Before

"A mushy middle is the worst — I wind up looking heavier than I am"

Before: This unflattering superskinny cut creates major muffin-top trouble.

After:

These structured shape-shifters ($54, YMI) do the dieting for Angela: The gentle bootcut offsets her tummy, and the high-contrast stitching helps fake a waist.
