Yes it is!
Exchanging for another size is no problem at all of course, and even exchanging for another design is fine by us; people can change their mind, simple as that. Both exchanging for another size or design is possible subject to availability to stock.
We do want to point out that some designs have a different price than others, for instance our licensed designs. If you'd like to exchange your suit for a design that is in another price range, we will either refund you the difference or contact you for an additional payment.
