At 5-foot-5, Holliday, real name Tess Munster, doesn't fit into the mold of traditional plus-size models, who might typically be a few inches taller and be between sizes 8 and 16.

"I think we're the only agency with a model of her size. She is by far the largest model I have in the [Curves] division," said Anna Shillinglaw, the owner and director of MiLk Model Management, the agency that signed Holliday after seeing her on Instagram, to the Daily News.
