Washing Lolita OP

Hey everyone,

I wanted to ask if anyone knew if the Swan Lake OP from Meta can be machine washed or even washed at all? It really needs a wash but Ive heard stories that the print bleeds. Does anyone know what part ?

I asume it may have to be drycleaned but Iḿ not really sure.

Iḿ appreciate some help, really want to wear my lovely dress again :)
