Plus Size Girlies Problem

Problem/Goal: Struggling to find a Plus Size Dresses

Context: I'm a plus size girl (2XL-3XL) and been browsing to Shein for a couple of weeks na and wala pa rin akong nahahanap na dress na bagay sakin for graduation, may nakikita man ako pero it's not similar sa mismong product like sa picture lang siya maganda. And i'm seeking for a help here na baka may marerecommend kayong physical/online store na pwede mabilhan ng mga formal dresses.

Previous Attempts: Multiple times

I've been looking for department stores in Mall but some of the dress is not fit on my style. What should i do?
