I've only worn it about 10 times, as it was for going out. I wore the hat about 3 times. This romper features an eye-catching all-over print design. The ivory and light blue colors feature Miffy, while the yellow features Boris, with different illustrations depending on the color, so be sure to check them out. It's a highly designed item that is adorable from every angle. It has snap buttons on the shoulders and crotch for easy on and off. A pile-fabric hat, convenient for sun protection, is also included, making it useful for walks and outings.
