I have by my own admission a larger bottom and thighs esp. compared to top half. So classic pear. I have therefore always gone for darker colours black, dark grey and navy. Even jeans are dark rinse! But I am getting bored. I keep looking at red trousers! Will I look even more out of proportion? And the whole red trouser thing - can you carry it off without looking daft? I
If you balance the red with a bright or matching item with width/shape round the shoulders it should work - for example a jacket, shrug or long sleeve top with neck/shoulder detail. If you want to slim your hips, some wide leg trousers offer a softer shape than skinnies (but I tend to be of the "be the shape you are" camp and just make sure clothes fit well).
