I had the same problem when I got some short kameez made in Pakistan. It made me look box shaped. My aunt got me made some and they were awesome. I think its important to have a good tailor who can make different style suits. Everyone can make plain shalwar kameez but not everyone can make good patialas and anarkalis.
Fitting seemed good but overall there was something funny/wrong about my short kameez. Darzi just didn't cut it good.
