bra size help ?

franchesca

can someone help a girl out😭 i’m 15 and every pink store i go to they tell me a different size?? i got fitted recently and the first store told me i was a 36dd and another store i went to they said i was a 32d. Another even told me i was a 32c?? I currently wear a 32d that fits fine because probably of how stretched out it is. But when I went to the store to buy more the 32d bras were too tight on me? And tips or help please ?
