Clothing help?

Hi,
I am an avid horse person. I lunge, ride and run with my horse. I am starting to run and do other higher impact workouts lately. I am having trouble with pain in my boobs from running. I am a 38d and I come up from the sides. Can anyone suggest a type of bra that can support me better that is not really expensive? Also I would like to know some clothes that would not be tight and confining but would still work? Be aware that I am 4ft 8 and 138lbs with most the fat in my midsection. I also don't have a ton of money to work with eaither. Please and thank you.
