I bought these for myself shortly after Christmas.  I like to wear a plain old t-shirt and comfy bottoms to bed.  I am pretty picky.  I want soft, durable, cute and cotton.  I got everything I wanted with these.
Also I am 5FT 2IN so I usually swim in anything not petite in length.  I bought an XL and I wear a size 14.  These are great, they do not bind or hug too tight. They are cozy but do not make me hot.  So like my subject reads.  I bought a second pair after 3weeks of loving my first pair.  Great price and I will probably buy more.  They will work winter through summer.
