Elektra actually laughs at the idea. It makes for a ridiculous picture. That's levity they could always use so she enjoys it for what it is. "I don't think you could fit your arm into my costume." She points out frankly. Her waistline might actually be the size of one of his arms. (Depending on the artist.)

"If you are interested, I could pull some strings with my fashion designer." She teases. Of course she has a fashion designer. Who else would fill such an insane order?
