This racerback tank t-shirt pattern is very functional because you can use any double jersey fabric and make it. It is not meant to be tight on your belly and is higher at the front than the back. It goes perfectly with the sports bra we have already worked on. A box pleat on the back will help accommodate a larger chest area. This racerback tank t-shirt pattern has only three pieces so it is easy to assemble and sew. This top is easy to make in a couple of hours.
