I need clothing/fashion advice for summer...?

I am a little overweight and very self-conscious about my legs. I carry my weight evenly all over so I don't look ridiculous, but I am self conscious about my legs...Mainly my knees. I need help with clothes that will help camouflage them without making me look frumpy and old. I'm okay with capri pants, but I just have trouble finding ones that look good on my frame.
