Forget Yahoo, it's a waste of time. Go with Adwords and create HIGHLY targeted ads for your products. Use buying keywords, for example keyword "buy republic light jacket" and link it to your products page for specific item,
REPUBLIC Light Jacket - Stars Fashion
I recommend you visit some competing websites and mimic what they're doing to get you started. First off change your font to something a little more pro.
Your website looks great by the way.. all except the finer details (which are very important).
For example your homepage where you say this: I am offering branded products and my prices are BEST around the market!
After years of work in an import company, which imports branded products to UK market, I have started my own online shop.
Through the experience and contacts gained I am able to offer huge discounts on all of my products!
People do not like to put their trust into a ONE person organization.. instead of "I", use "we". Not only that.. this area of your website should instead be used to promote any offers you are having at the moment, for example fast shipping, lowered prices, etc.
The way it is now is a turn off.. a negative I like to call it.
You need to get rid as many negatives as possible from your website. Negatives are something that may turn someone away from your site.
Again look at your competitors and mimic what they have on their websites. Then use Adwords to bring in targeted traffic while you build up your SEO.
Good luck!
