It's great to see you placing your first order with us, although of course it's a shame you haven't quite found your perfect fit on the very first try. Never fear however, as we make returning and exchanging items very quick and easy with Rebound.
Depending on where exactly the shirt is a little tight (around the neck or in the body) there are two options - for the first, moving up a neck size would be the best option. For the second, switching from the Slim to the Classic Fit will provide additional room in the body, as well as being slightly longer. Our Customer Service Team are available each and every day to offer assistance with sizing or fit-related queries, and can also help log a return should you need them to. In the meantime, there are a couple of links below to help understand the sizing and fits of our shirts -
