I think you have done the right thing changing bra’s honey,the macoms are good but not everyone finds them comfy,yet some swear by them too,think its down to the individual,you boobies are bound to feel heavy until you get used to them,lets face it they were a lot smaller before so you will take a little time adjusting,wow how many would wish their’s had grown over night you lucky thing,lol,take it easy honey,xxxx
