SIZING: This style runs true to size and is made to fit snug in the chest and arms. We recommend ordering the size your little one will be in during winter when they will wear this most :) We don’t recommend sizing up in this style as you do not want the pants dragging on the floor. Typically if you are in between sizes our customers have found ordering the smaller of the two sizes has worked better. (Example if inbeween an 5/6 go with an 5). All of our models in the listing pictures are wearing their true sizes for reference. •••••••••••••••••••••• SHIPPING SPEED: This item is scheduled to ship late October/Early November.
