How to get rid of baby belly and what to wear to hide it?

i had a baby nearly 5 months ago and managed to get back to my pre-pregnancy weight (which was a little on the heavy side for me as I used to be a size 10 but was pre-pregnancy and currently am a size 12-14) Im fine with being a this size but the only thing is everything has shrunk back but my muffin top and huge belly. I still look 6 months pregnant. I cant wear any clothes to hide it as if I wear tshirts they look too tight and i look pregnant so if i wear aline/empire/floaty tops they just look like moo moo tops and i look even more pregnant. I dont know what excercise to do to help tone it as I dont want to do extreme excercise and lose weight (I dont really want to lose too much weight as Ive already lost most of my once big clevage!!) are there any excerises that work for this or any clothes that can cover it up as it is really getting me down to the point of me cancelling seeing friends at the last minute as I feel too fat in whatever i wear. any experience/advice would be great thanks! :)
