If you have knowledge and passion about western wear, starting an online clothing store selling this type of clothing can be enjoyable and profitable. Starting an online store requires less start-up money than a traditional brick and mortar store, and the overhead is less--you won't have to pay for as much staff, a building, utilities or store fixtures. However, before opening an online western clothing store, you'll need to develop a thorough plan.

Choose a niche for your western clothing store; this will help you market your store more effectively. For instance, you can specialize in retailing authentic cowboy boots and hats, custom leather belts and buckles, western dresses and women's apparel, or clothing for ranch hands and farm workers.

Obtain the permits needed to be a retailer in your area. This may include an assumed name certificate or DBA, resale permit, tax identification number or employer identification number, also known as an EIN.

Buy a domain from a domain name registrar, and choose a name specific to your niche. For example, if you sell custom belt buckles, the domain name “CustomWesternBuckles.com” is better than “BobsWesternWear.com.”

Decide where you will store your inventory of western clothing. A dark space that is free from dust, moisture and odors is ideal; an empty spare closet or commercial, temperature-controlled facility would be appropriate.

Sign up with an e-commerce solution that includes a merchant account or payment processing, hosting capabilities, built-in templates and a shopping cart function. This will prevent you from needing multiple accounts for the different elements you need to sell online or having to hire a web designer.

Open wholesale accounts with western clothing suppliers. To open an account, you may be asked to provide business documentation or place a minimum order amount ranging between $150 and $500.

Buy retail and shipping supplies for your online western clothing store, such as corrugated shipping boxes, adhesive labels and protective bubble wrap.

Promote your online western clothing store by listing your store in print and online business directories, placing ads on websites and forums frequented by your target market, becoming a vendor at local rodeos, carnivals and flea markets, or starting a promotional blog.
