This is a size 1X, so if you normally wear a 16-18 it should be perfect! If you normally wear a 2X, this would be a bit closer fit. The top is shown on a size 16 mannequin, but check the measurements to be sure it will work for you:
Bust (at armholes) 54"+ (27" across the back without stretching the knit, more than that with the gathers in the front!)
Length from shoulder to hem: 33
This Top is from the Red Panty Designs clothing line, and has a cloth label stitched into the lower body.
