Got this for a friend for her birthday she's around 240 to 250 larger tummy larger upper arms fit her fine. Drapes nicely. got it in a 2x for her. Use this for basic sizing guidelines. Look at the chart for the sizing...$14.99 from Amazon Prime  for the navy blue and white floral on white background... very fine cotton knit gauge very very lightweight. She loves it and uses it as an over sweater as well as a top... let me be blunt if you wear a bra that makes a bumpy front appearance this is not the sweater for you.
