Cream Wash & Wear Shalwar Kameez

I ordered 10 suit till to date i have a suggestion that shoulder size of medium is smaller than mentioned so kindly check it again it is 18 in medium but not perfect so kindly increase medium size from 18 to 18.5 and arm size is too long so kindly check its pleated with cuff

At last shalwar size of medium is must be 40 thanx and some time length of kameez is longer than mentioned size at medium size
