Someone with a pear shaped body has a smaller upper body (small shoulders, chest etc.) , but larger hips and thighs. Being a pear does not mean you have to lose weight! There are lots of ways to flatter a pear shaped body. It's all about creating overall balance. I myself have a pear shaped body and I don't have trouble finding clothes that fit and look great, you just have to know what to look for!
I'm going to break it down into different categories, eg. jeans, shirts, shoes etc.
Jeans: When shopping for jeans you want to look for dark washes, fading and rips aren't good as they will draw attention to your lower body. The cuts that flatter pear shapes are boot cut, and straight. Try to find jeans that have a mid rise, the extra bit of fabric at the top will help suck in any bit of tummy you have.
Tops: look for bright tops with pretty designs, drawing the eye upwards will help keep attention away from your heavier lower half. Any top that nips in at the waist is great, because this is the smallest part of your body. scooped necklines look great on a pear, and v-necks can work, but its better to stay away from them. Ruffles and other little details at the top of a shirt are fantastic because they draw the attention upwards, don't be afraid to look for embellished tops!
Skirts: A-line skirts look fantastic on pears. Look for skirts that end just above the knee and are in a nice dark colour like black, dark brown, navy blue etc.
Shorts: Look for shorts that end just above the knee, or right below the knee. Anything that ends at mid-thigh will emphasize the size of thighs, and might even make them look bigger. Once again, look for dark colours! Also, if you want to elongate legs look for shorts that have a cuff on the bottom, these are really cute and do help elongate legs!
Shoes: There aren't many rules for shoes when your a pear, just grab whatever ones you want! But stay away from short boots in the winter, and look for ones that go to mid-calf or your knee.
Dresses: Wrap dresses look great on pears! Just like skirts, you want to dress to end just above the knee. A nice "swooshy" fabric in a bright colour would look great! Wrap dresses work well because they nip in at the waist, giving you a nice hourglass look.
Jackets: Jackets should end right at the hip bone, visually this divides your body in half, creating perfect balance! Like tops, look for jackets that nip in at the waist.
Hopefully this helped!
