You only plan to invest 30,000-50,000 yuan, so the store can't be too big, just below 10 square meters.
Decoration needs to be based on the style of clothes you sell. Shenzhen is the best city for women's wear in China. You can find good goods by visiting the wholesale market.
Take as many goods as possible for the first time, take the code with the most buyers, M code, and try to unify all styles. Don't simply hang up clothes, put them together or let models wear them, which is more exciting.
If you are really scared, don't be afraid to lower yourself to be a clerk in those clothing stores downtown and learn from others. It doesn't necessarily take long, just a few months.
I don't advise you to find a brand, because the brand is not enough for your money. Very unrealistic. Don't think that the head office can help you make money, because if it is as good as they say, will they be short of tens of thousands of dollars to open a shop? Nobody will run it, will they? They are afraid of having money and no one to work for them. Go to the wholesale market to purchase goods yourself.
In fact, the investment in clothing is not large. In Shenzhen, the main place is site selection. The location of a better storefront is estimated to be more than 30 thousand, and it needs to be renovated. And now the competition in the clothing market is fierce, and you have no experience. I know that many girls dream of opening their own stores, and clothes are every girl's favorite. You might as well accumulate some experience first and then carry it out when you are absolutely sure.
