This stretchy top is so soft!  It measures 17" under the arms, is 31" long in the back and 26" long in the front.  They are known as "high-low" shirts (?)!  I usually wear a medium and I could wear this top as it is stretchy.  The brand of the top is Color Bear and is 95% rayon and 5% spandex.  Again... it is super soft!!
