Winter dons a blonde wig and sequined outfit for new Holiday Instagram shot.

The Modern Family star took to social media to wish her 2.7 million followers a Merry Christmas and looked almost unrecognisable.

Donning a platinum blonde wig and a bright dress with a red sequined bodice, the actress captioned the pic ‘Santa Baby.’

Winter tagged the company Trashy Lingerie in the pic which created the custom-made dress for the actress. The company has been making handmade lingerie for Hollywood since 1973.

Winter also donned a red velvet pullover complete with white fluffy trimmings and pompoms.

The star accentuated her never-ending legs with a pair of silver, sparkly heels.

Her followers seem to be loving the snap with one user writing “I would rather have you come down my chimney rather than Santa Clause,” while another wrote “All I want for Christmas is you Ariel Winter.”

The 18-year old has long been an advocate for body confidence and self love constantly encouraging her followers, especially young girls, to love themselves for who they are and be confident in what they wear.

While Winter occasionally comes under fire for her outfit choices, there’s no denying the actress is extremely vocal on encouraging people to be comfortable with themselves.

The young star has also recently found love after she was photographed making out with 29-year old actor Levi Meaden in November.

Winter took to Instagram to post an adorable photo of the loved-up couple captioning it with a love heart and an emoji of a rabbit.

Winter broke up with her boyfriend of two years, Laurent Claude Gaudette, in June but seems to have happily moved on with Meaden. As well as spending the holidays together, the pair holidayed in Mexico earlier this month.
