The Midsommer star has been known to support fans of her characters dressing up as her*.
Pugh even told Arianna Grande to buy the 33-pound flower dress from Midsommer that was up for auction.
"DO IT! Halloween will never be the same."
Unfortunately, this year it will not be as easy for fans to dress up as their favorite Russian spy turned hero.
Pugh appeared to be in front of a New York City Halloween costume shop.
Her caption read:
"What the.. Apparently Yelena didn't make the cut."
"GUYS. I LITERALLY TALK ABOUT POCKETS IN NEARLY EVERY SCENE. Halloween= A LOT OF FREE SWEETIES."
"May I remind you that the vest has 'A LOT OF HANDY POCKETS'.. Costume+vest+POCKETS= someone who came prepared."
"IT IS with great importance we understand how vital Yelena is for Halloween."
"Rant over, thanks for listening."
Pugh's fans were behind her on this one.
Although, it doesn't seem like it has as many pockets as Pugh might be looking for.
