Joining and doing it yourself have their own advantages. If you join, you must investigate each other clearly, otherwise you won't get the goods you want, or give you a pile of goods when you don't want them, and you will be miserable!
Do it yourself Do you know where to get the goods now? If you know nothing about the clothing industry, I suggest you don't go into the water.
Conclusion: If you have no experience, go to an experienced place to study first. College students have potential, so don't be blind.
