I did it now have a small chain. The #1 thing is going to be money. There is really nothing you will learn in school to help you. Some classes on sales, marketing, and taxes, computers (for your own website) will make it a lot easier tho,When the day comes that you actually want to do it, let me know I will give you the step by steps version.
money is key! you have to have constant look over it. if your income becomes less every month then you need to think of a new way to get people back into your store. you got to work your hardest at selling whatever merchandise you have. a buisness, accounting, or managment degree would help with this job. (mainly management and buisness) sorry for being brutal lol. good luck
it is not easy to open a clothing store.so please carefully.i know a website who sales clothing, maybe you can have a look. www.fashionsaler.com
