This T-shirt features a back panel made of a different fabric. The front is made of a thin, light blue knit fabric, and the back panel and below is sewn with a thin, blue-toned polka dot fabric (slightly sheer). An iron-on transfer has been applied. It is 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. Please forgive me if you are 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 by cozy Fluffy, fluffy
