Runs true to size! If in between sizes the smaller of them will have shorter length and some size up for longer length.
Ella is 24 lbs 34” tall wearing an 18 months.
Callan Kay is wearing a 2T she is 27 pounds and 37ish inches tall. Perfect IMO (shorter length).
Claire is 27 lbs. 36" wearing size 3 long.
Vivian is 32 lbs and 38” wearing a size 3 (shorter length).
Zellie Grace is wearing a 3T with stats of 35 pounds and 39 inches tall. I could have sized up for longer length but I just love the fitting of the 3T on her (shorter length).
Sophie is wearing a size 4T. She’s 35 lbs. 41” tall and it was a perfect fit.
Lillie is 39 lb and 43 in; Harper is 33 lb and 43 in. They are both wearing a size 4T. I recommend sizing more for the LENGTH of your little.
Avery is usually a size 5 approx. 41 lbs. 44" wearing size 5 (perfect fit in width but could have sized up for longer length).
Claire is 49 pounds and & 42 inches tall. She is wearing the size 6 with room to grow & extra length.
