谁敢素颜小白衫帆布鞋溜达
[shéi găn sù yán xiăo bái shān fān bù xié liū dá]
'Who dares to casually stroll around plain-faced, wearing a simple white shirt and canvas shoes?' Suggesting confidence without the need for embellishment, showing pride and ease in one's natural state, not overly reliant on fashion or makeup for validation.
