Hate to say it but expect this to happen for a long time to come, especially since you're not a super chain like Express, Abercrombie or Hollister. People aren't going to just jump in and know your shop is around, or, even care - You need to think outside the box to advertise your stuff in ways that people will actually see.

Hire a clown to advertise your store outside.

OP, starting a business is tough. Don't be discouraged if business is sparse at first. Your store won't immediately be popular. It takes a lot of work and time to get there!

I'm sorry I stole your sign, I didn't know it was a clothing store... I'll buy a feather boa to show my sincere apologies.

where the hell did you open your store at that someone would steal your sign? ghetto

marketing dude hope u hired someone to do demographics in your area. & get your name out there! good luck!!

Signs signs everywhere theres signs... Well except at your store.

You should use the google keyword tool to research terms in your area that drive search traffic for your business. you may find google insights and google local business center helpful. good luck!

Would have been worse if your mom was stealing your clothes.

well ask yourself this, is your clothes shop appearance something somebody would want to go into? good luck for the future anyway
