I bought this Faded Glory 4 in 1 system jacket in a size 8 and the jacket that forms the inside layer was a size 6-7. They were connected with a plastic tie strap that could not have been tampered with. Is this the design to have the inside jacket at a smaller size than the coat? I want to check to see if they are ALL that way before I take inconvenience of going all the way back to the store. Let me know, thanks!!
