Brownies progress to girl Guides at the age of ten so for those with daughters in the Brownies, when they reach the age of ten, the uniform will change to the Guide uniform. There’s only five items to complete the Guides uniform. A polo shirt, hoodie, long-sleeved top, dress and skirt. When wearing the Guide uniform skirt, a black pair of leggings or tights is worn under it. If wearing the dress as part of the uniform, another item should be worn under it such as the Guide’s long-sleeved top.
