At present, most universities wear personal clothes. In addition to military training, you can send some training clothes, and there is basically no school uniform. But Tsinghua still has a big vest to play, which is the symbol of Tsinghua.
So generally speaking, colleges and universities in Tsinghua University, for example, will give everyone a professional T-shirt from Tsinghua University and a big white vest with Tsinghua University logo printed on the back.
As far as I know, college students generally don't have uniform uniforms, but they may be equipped with uniform clothes when attending some special activities.
