I recently purchased my first shirt from Yiume. I have been burned by other online short companies that state their products are all cotton only to receive the products to find that they are polyester or rayon. I bought my first shirt as a trial and it was exactly as advertised! I have bought four additional shirts in the last month from them, and this was my latest purchased. I LOVE it! The only thing that I would ask is that Yiume offers shipping methods other than USPS. as there are always problems with them that do not occur with FedEx or UPS.
