In addition, my suggestion is not to lose military training clothes. After all, the style and color you bought online or in the store are likely to be different from those issued by the school, which will be somewhat inconsistent.
It's convenient to buy online, whether it's Tmall, Taobao or JD.COM. You can find many types of military training clothes through search, and you can choose the appropriate size according to your height and weight.
I'm not sure about the clothing store. You can go to a special clothing factory, labor insurance store or military field survival store in your area. These stores should be selling school military training clothes. If you buy offline, you can know the size that suits you better than online, and you are more assured.
For most students, especially college students, the military uniforms must be set by the school. For example, in our school, when we are older, we will collect classmates' clothes, pants and shoes sizes. At that time, you can get it downstairs with WeChat payment and buy it with the school, so that the styles and colors are the same and the military training will be more tidy.
