    Too small, short sleeves/pants length, too expensive

    The 4X is definitely not a true 4X, as the pajamas were tight all around. I've ordered 4X from lots of different online stores, always checking the size guide, and didn't have problems. I think the size guide needs updating for these pajamas. The sleeves and pants length were also too short. I'm 5'9", so a little taller than average, but still I'm able to find other pajamas from other online stores that don't have this problem. For the cost, these were exorbitantly too expensive for what I got. I was really disappointed 😞

    Well made, great material, great fit and very comfortable. I'm a medium pear shaped petite and find the fit true to size once they've been washed a dried.
