The former Coronation Street star sizzled in a fitted suit and white shirt... but it was that incredibly voluminous hair that has us all talking!
Michelle, 26, gave us a glimpse at her luscious girls via Twitter earlier in the day, a very different style to the sleek locks she usually favours.
The actress had a huge smile on her face as she posed for photographers and also took time out to snap selfies with the scores of fans who'd queued up outside the store to see her.
"The Liverpool girls are so glamorous and it's great to see so many people out today, despite the weather," she told Liverpool Echo. "The new store looks great and I can't wait to have a good nosy around. I'll be stocking up on new season fashion."
Michelle took her first steps into the fashion world earlier this year with the launch of her autumn 2014 range for Lipsy.
"I think you should be confident and comfortable with what you're wearing. If you're not comfortable, don't wear it, because you can always tell, even in how you hold yourself," she told Reveal.
"I like jumpsuits because if they fit well they can look very classy. I like the tailored suit look as well - tight pants with a nice top tucked in and a suit jacket. I also love bodycon cocktail dresses, not too short though, usually just above or below the knee."
