Go by measurements. 3 small buttons if you want to use. Great as bathing suit coverup or additional coverage for leggings. Like a vest but so many gorgeous details. Says 2xl but fits xl Tiered effect with crochet on top, then tulle section then another tier of crochet and lace and then tier of tulle ending with lace bottom. Large opening for arms. I’m an Xl and it fits me as size 14. So 12-14. Comfortably 31” back of top to hem 22” pit to pit
