Excellent Quality and Value
Color: Light Blue White Plaid, Size: Small
This shirt is an excellent value, looks great on my husband and comes out of the dryer looking perfect. However, I ordered this plaid and another plaid pattern and received 2 of this same plaid. I will seek out this brand in my future purchases for the high quality.
