3X lightweight swim cover pullover fits like xL

This is at tan and cream striped pull over long sleeve shirt. Elasticized cuff. the lace down the sleeves and across the chest area feel like a cotton fabric. The tag says 3XL but this is definitely not much bigger than XL. I purchased this with the intent to use it as a beach cover-up but it is too small for me. pit to pit 21.5 inches shoulder to front hem 27 inches. Shoulder to back hem 32 inches. Sleeve 24.5 inches. The buttons are functional but very tight therefore would be better as a pull over. Beautiful light fabric. 100% viscous. Slight run at the bottom button where pictured 460523PB09
