For women, these tees are a great value for around the house wear.  I'm an XL in women's size and the Large men's fits great.  They are great for sleeping in the winter.  In the summer I take scissors to them, cutting the sleeves in half, cutting the neck ribbing off, and some off the bottom as well. I don't bother sewing the raw edges. When I bought some were priced at under $7.00, such a deal!
