Very pretty top from the M&S Indigo Collection. Main body is soft to touch "T" shirt style 100% cotton. There is an elasticated gathered section on the sleeves with a small frill and the bell section is in a thin floaty very fine mesh in 100% viscose.
Label states Size 10. Here are some approximate measurements taken with the top lying flat and unstretched to help determine fit:
Bust, armpit to armpit: 35 inches
Length around hem: 38 inches
Length at the back: 23 inches.
In great condition.
