The 20-year-old was pictured arriving in the UK at Heathrow airport earlier today (17 July) and perhaps in anticipation of our English weather being pretty chilly (like it usually is), she refrained from flashing her flesh and covered up in the interesting all-in-one.
Lately, Miley has been seen in an array of risqué and skimpy ensembles but this time she opted for something a bit more comfy and low-key.
She teamed her tweed boiler suit with a pair of black and white creepers, a black leather rucksack with chain straps and some black sunglasses, while also clutching on to a magazine, which no doubt kept her occupied on her flight from the States.
It seems as though Miley has had an extra hectic work schedule recently, since she has been spotted making a number of appearances on talk shows and radio stations across America to promote her new music.
Just yesterday (16 July), the pop superstar made a pit-stop in New York to visit the set of Good Morning America and almost gave us an unintentional peek at her boobs, by going without a bra as she donned a long black dress.
Well, there's no risk of her flashing us in that boiler suit - although the day isn't over yet!
