Helen wrote at the time: 'I cant lie I'm really embarrassed about my boobs.. I just wear whatever dress I think is prettiest x'
Just a week ago she vowed to tone down her provocative image in favour of a more demure look after facing Sherri Hill Long Prom Dresses criticism over her choice in attire.
And it appears as though Helen Flanagan, 21, is committed to her new look, stepping out today in Manchester looking almost unrecognisable.
On top of covering up her ample curves in a demure ensemble, the former Coronation Street star also went without her usual full face of make-up and super-styled hair.
Helen looked a little tired but showed off enviably flawless skin with her new natural look, and threw her hair up into a careless bun.
She is clearly relishing the freedom of going au naturel, tweeting over the weekend: 'No makeup days are the way forward.'
The actress wore skinny jeans, studded loafers, a fur Sherri Hill Short Prom Dresses jacket and leopard print scarf as she strolled through Manchester city centre.
Fans had become used to seeing Helen step out in ludicrously revealing outfits and over-the-top make-up over the last year.
But her about-face came after she faced criticism for a particularly low-cut and flesh-coloured Jean Paul Gaultier La Perla dress that her cleavage threatened to spill out of.
After seeing the pictures in the press Miss Flanagan tweeted that she felt 'embarrassed' and vowed to cover up from now on.
Then, in a bizarre way of proving her embarrassment, she tweeted a photo of herself in a floral top as she showed off her plump pout, staring seductively at the camera.
Soon after, she added another photo in a more demure, long-sleeved black top, saying: 'Polo necks for me Cheap Sherri Hill 2012 Sale Online from now on.'
