Make the least of your thighs with trouser-cut jeans adorned with a full leg, which creates the illusion of length. The user-friendly, boot-cut style denims are also fine for balancing out a curvier lower half. Go for dark wash in either style jean -- it's definitely a solution to slim your legs.
Try on a high-waisted pair of denims if you want to bring out your curves. If you pick a pair that has a high waist and a wide leg, it will also work. Tuck in your shirt or wear one that comes to your waist to get the full effect.
Don a pair of straight-leg jeans if you want to lengthen shorter legs. Straight-leg jeans won't work well on everyone, however, especially if you have curvy thighs. In case of curves, look for a boot cut or more relaxed fit.
Go skinny in the jeans if you dare to wear them. Pick a pair with a bit of stretch built in for control, as well as a longer hem to create length. Pick dark washes if you are curvy. Choose lighter colors if you are more straight up and down.
Bring some balance to your hips and thighs with some flare. Although not quite a bell bottom, these type of jeans can add style to your wardrobe while drawing attention away from fuller areas.
