you can set up a clothes shop in your neighborhood or in bluewater village (or a created shopping area.) The basics: you need a rack of clothes, a cash register and someone working the cash register. And i dont know if this is required but you might put up a changing station also. oh and an open/closed sign. and i think thats covers it. Thats just the basics, i myself really havent created many businesses so someone else can back me up and fill you in on the details. (if any)
I've done very little with running a business but I have heard that you can't do a clothing store as a home business. You need to buy a community lot store for it. Also, besides everything else that Jazz listed, you also need a business license. You get that by using the phone. It's one of the options.
I believe the close are under miscelleneous>miscelleneous. if not, under the decorative>micelleneous. If not sorry lol.
