This is a T-shirt with a woven fabric panel on the back. The front is made of a thin, light blue knit fabric, and the back panel and below is sewn with a thin, blue-based polka dot fabric (it's somewhat sheer). An iron-on sheet has been applied. It's attached firmly, but may peel off during washing. If it does peel off, place a sheet of parchment paper over it and press with a medium-heat iron to reattach. Shipping may take some time. I apologize to those in a hurry. This item has been carefully sewn using a 2-needle, 4-thread overlock machine and an industrial sewing machine, but unlike ready-made products, there may be slight stitching imperfections. Thank you for your understanding. pattern cozy Soft and fluffy
