I know building a brand takes time. It won’t happen overnight.
Congratulations for this great new initiative, it always takes time to build a brand, but at any point of time, we have to consistently work hard for at least 8-10 years and then only success comes. I guess, you already have spent few years coming this far, so maintaining the quality and winning trust is the only next hurdle for your success. Once that is done, just keep the momentum, bring innovations and you will be all set.
Few other suggestions : In the site, if I go and view an individual t-shirt, under Product Specifications I see Size worn by Model : XS,S,M,L,XL,XXL,XXXL, but then that's not true. There is no model and you don't have sizes XXL or XXXL, so try to put accurate information always. And it will be good to have a working phone number in Customer Care Address.
Again congratulations for a new beginning.
