Girls Aloud – the UK’s most popular girl group are on tour at the moment. So to celebrate that fact this week is officially Girls Alound week at Denimology – each day we will see which jeans these pop babes are wearing. Today we start with Cheryl Cole who was photographed wearing a pair of 18th Amendment jeans whilst in Cardiff. If you compare this week’s photo (shown above) with one of her taken last October (shown below) wearing the same pair of jeans it seem pretty obvious that she has lost a lot of weight. Either way the jeans still look great.
