On November 11, 2015 Roblox announced on a blog post that they were hosting a contest called the ROBLOX T-Shirt Design Contest.
 Those who won first place in each category will receive $5,000 ROBUX, plus 10 free shirts of their design in any size.
In order for users to enter users had to:
- Create a high-resolution image with your design. The image should be at least 1200 pixels wide. If you’re doing both a front and back design, each image needs to be at least 1200 pixels wide. PNG format is preferable for images.
- If you’d like to mockup your image on a t-shirt, you can download this template (front and back) which shows the area we’re using. Be sure to send us the full design as well as the mockup, too.
- Fill out this form and upload your design by Friday, November 20 at 11:59 p.m. PT. Make sure you put your ROBLOX username in there so we know who to credit, and which category you’re entering.
