EUC Purple Puff-Sleeved Shirt

I love this shirt but my arms are a little big too big for it!! Lovely rich purple color, sleeves are puffy and do have an elastic band at the end (see pics). Measures 17” pit to pit and the sleeves are approximately 5” at the cuff with elastic and very little stretch. I’m a 36C and it fit me just fine except for the arms - mine are over 11” in circumference. I lift 😩. Non smoking home, thanks for looking!
