Chanelle McCleary certainly made quite the entrance as she arrived in a barely-there white dress that struggled to protect her modesty.
Making her way into the Borehamwood bungalow to join her other housemates, the Manchester lass gave onlookers an eyeful as she flashed her knickers in the revealing number.
But that wasn’t the only thing the brunette needed to worry about as her ample assets almost spilled out of the halterneck gown.

Going braless, she definitely would have made an impression amongst fans as the low-cut neckline left little to the imagination.
However, Chanelle – who has appeared in previous reality shows – left host Emma Willis and those watching at home horrified with her comments.
During her VT, the new housemate said: "I'll go in there, shake my t**s and fk s**t up."
And talking about her eye-catching entrance, the former Take Me out contestant left Emma in shock as she said: "I thought, 'I'm gonna slip, my f***y flaps are gonna be out!"
