My advice: forget about making a great landing page--you need a simple page up now, as in today. This is getting buzz. Right now you should go to weebly and set up a splash page for dress.me that just has a simple email capture form for people who want to be notified of your launch. Find a friend or pay someone hundreds of dollars to do this today if you don't know how. If I don't get an email announcing launch, you can bet I won't remember about your service.
Good luck, and it sounds like a great idea if you can make it work!
