Ballet shoes, forty or fifty.
And tight training clothes. I prefer black, slim, hehe! Navy blue is also good!
Don't forget the ballet socks.
All the above are necessary, and 200 yuan should be enough.
Also, you can buy a cotton sweatshirt, which can be worn outside the sportswear, and then buy a pair of black pants, up to 50.
That's all I remember. The quality of these things can be seen at a glance, and it is easy to identify.
