Can doing only yoga, a little cardio and Pilates help you get slimmer legs in 2 months? How much calories should I eat also?

I had being doing exercises like squats and lunges, i dont like the fact that they have only made my legs become bulkier. So by doing ONLY yoga can I lose weight and get slimmer legs? also can you tell me how many calories or what should I eat and how much should I exercise to lose a lot of weight and get slimmer legs in 2 months.
