We ordered a 7-8 for my small (in stature and build) 8 year old. She is about 48 and 3/4 inches and is the 2nd or 3rd smallest kid in her grade. The top fits ok but the cuff hits her about 2 inches above the ankle. We are going to keep the costume because it otherwise looks pretty good and the shipping already took over two weeks. We like the jumpsuit, but beware that it runs small.My now 5yr old son has been obsessed with squid game ever since it got big. Even though he's never seen it lol (tographic for his age.) He made his own costume from red clothes lol. He wanted it for Xmas but it was gonna take too long so I ordered it for his birthday in April. He was SOOO excited to put it on it was money well spent, I sized up one size because he likes to wear his suits everyday so I'm constantly washing them so I didn't want it to shrink. Very well made and good breathable material. Im so happy I got this for him, hes so cute in it!Costume looked exactly as described and the fit was perfect. Grandson loves it!Muy buenoIt didn’t fit ask for a return more than a month agoMy son loft it perfect costume and true to its size
