Oversized Zara Pastel Button-up

Flowy tie dye/watercolour oversized satin effect button up from ZARA. Missing the bottom button but because it's quite flowy I never found it noticeable. Cut the fabric care tag, but I think it's polyester. Size XS but is very long and oversized so would likely be fine for a small. I'm 5'2 and it goes past my bum. I often wear it tucked in, or over bike shorts for a shirt-dress kinda look. Also very cute just worn long and loose over trousers or leggings.
