Well, I really like these pajamas. They are perfect for me. However, I ordered the petite large and they fit me. I wear a size 4 in most brands and weigh 115 lbs. This is to say that these pajamas run pretty small. The shirt was roomy for me, but perfectly acceptable, but the pants were almost tight. It seems to me that the sizing is off somewhat if the L fits someone who is a size 4. Beware about sizing when you order. Otherwise, they are well-made and I really like them. Medium weight so acceptable for fall spring and winter. Might be a bit too warm in summer unless you keep air conditioning up high.
