I bought this used! I've worn it once. I'm not very familiar with the size markings, so I apologize, but please check the photos! I think it's probably 9m, around size 75. There might be some slight fading due to washing, which is typical of navy blue, but I don't think it's very noticeable. Also, I think there are no particularly noticeable stains. This is a used item. Please purchase with the understanding that it is used!! 【Design】 This Ralph Lauren romper has a navy and white striped design, which is simple yet stylish. 【Material】 It uses high-quality cotton material, which is gentle on a baby's skin. 【Functionality】 It has snap buttons at the bottom, making it easy and convenient to put on and take off. - Brand: Ralph Lauren - Color: Navy and white stripes - Material: Cotton - Design: Polo shirt style romper - Buttons: Snap buttons at the bottom - Embroidery: Polo logo embroidery on the chest Thank you for looking.
