So a week ago I decided to order this:
Boys' Fleece Zip-front Sleeper from Lands' End
In size L (14/16). I had heard that the Land's end pajamas were smaller than the Cherokee or Circo ones. When I opened the package I couldn't believe how long they were They were even longer than last years Target brand! I tried theme on and they fit much better than I ever could have imagined. The feet were however alot smaller than the Target ones but they still fit me.
In width they are smaller so they fit tighter. All in all fit was ok, in some ways better than the Target ones and in other ways worse.
Oh, and I am about 5'9 (175cm) and weight is about 165 pounds (75kg). If you are slimmer you could even be a couple of inches taller, maybe?
