You are kidding me,,, right? Who is your customer? What are the demographics of the neighborhood? What is the income level of your customers? You need to do alot of research before you can decide what products to carry, unless you plan on purchasing most of the clothing for yourself. You need to carry products your CUSTOMERS want.. now. that said, what you like may be what your customers like. If your a collage student in a college town, then I would assume your customers likes would be similar to your likes. If your a young person in an area of older folks, you need to carry what they want. You may want to check out
www.sba.gov for some advice on opening a store.
You may even want to work in a clothing store for a year or two to "learn" the business. Retail is a hard business, .. ask yourself, why would someone shop at your store, rather than one of the large retailers? How are you going to get people to come into your store, how are you going to advertise? Lots to research before you open. One of the main points to research is LOCATION< LOCATION, LOCATION.. MOST important in a retail establishment.
To make that point, when I opened my first store, I had the choice of two new strip centers. Across the street from each other. One was less per month, but the other was in a "better city'. I knew that people from City A (the "better one) would not shop in city B, but the folks in City B would shop in City A. I opened in City A and I was 100% correct, and only because I lived in city A. I knew that the location, even across the street, was most important.
Good Luck !
