As you can see, Rebel Wilson is in a more 'covered up' version of the shirt than her cast-mates.
Refinery 29 pointed out that even other cast members, including Anna Kendrick are in the more revealing shirt.
Ester Dean is the only other girl wearing the same top as Rebel.
Salvador wrote on Twitter:
"I let each actor decide how their costume fit, it was their choice, Rebel, Ester & Hana Mae wanted sleeves, #sleevegate."
"do a little research before you write a story, this pic shows all the variations of the top #sleevegate #really? #ugh."
"To me it is about dressing women however they look and feel great, whatever size they are. It's about choice, confidence and style! "
Thankfully that's all cleared up, because we really didn't wanna believe anyone was being fat-shamed.
