Very comfortable women's cotton boxers
Size: 12, Color: White Pack
These Comfort Choice women's boxers are comfortable and made of soft cotton. They are not bulky. On me, I,'m 5'2", they come down to about 2" from my knee. I wear them from fall through the winter. They give that little extra layered feeling. The legs stay down.I weigh 259 and wear size 13.

Product quality unpredictable.
Size: 12, Color: Vibrant Blue Pack
Disappointed in this purchase. I have purchased this type of shorts for sleep wear in the past and enjoyed them but the quality, fit and sizing has become increasingly unpredictable. This batch is so bad they fall off while I am sleeping anytime I turn in the bed the item slips off of my body. The elastic is so tiny it can't adhere to my shape. It cost too much to return the item so I am using it till I find a replacement.

Soft, but too short for my long legs
Size: 10, Color: Basic Pack
These are soft, but much too short in the legs, so that I have to continuously pull the legs back down out of the crease between my upper thighs where it creeps up into the crease btwn the thigh and stomach. If they were about 4-5" longer they would be a 5☆ rating for me.
