I hope this isn't too harsh - it is meant as constructive comment.
1) Welcome page - get rid of it. I want to see your products - not a splash screen that gets in the way.
2) If you don't want to get rid of the welcome page, make the entire page clickable. I don't want to search for some tiny click region just to enter your site.
3) "Shoes" and "Handbags" is only mentioned once on the home page. You want google to pick your site up so increase your keywords as much as you can get away with.
4) The label names on the front page should be clickable and go somewhere sensible.
5) You need alt tags for your images.
Otherwise I like it. The design works well I think.
