VGLOOK Unisex Christmas Halloween Witch Party Reversible Hooded Adult Vampires Cape Cloak (Blue/Black)

Would it fall off my shoulder's if I dont tie it?

Is this big girl friendly !? 😭😂 (being serious) I normally wear a 3X

What are the care instructions? Can it be machine washed? Does it need to be washed in cold water? Does it need to be line dried?

How would you suggest getting the wrinkles/pleating out due to it being folded in the package? Steam? Low heat dry?
