I purchased this from the PETIT KID online site in September of this year. I am selling it because it didn't arrive in time for the photoshoot and I was unable to use it. The size is 80, so I think it will be just right for a one-year-old. The following is a quote: A set of a neat romper and suspender pants ✨ The bow tie is removable, so it can be used for everyday wear too ♡ ▶︎ The bow tie is removable. ✔ color : One color ✔ size : 55 / 60 / 70 / 80 / 90 ✔ material : cotton 95% 55size : Total length 38cm / Chest 24cm / Pants length 21cm 60size : Total length 40cm / Chest 25cm / Pants length 22cm 70size : Total length 42cm / Chest 26cm / Pants length 23cm 80size : Total length 45cm / Chest 27cm / Pants length 24cm 90size : Total length 48cm / Chest 28cm / Pants length 25cm
