what is 5t

5T is a specific clothing size for toddlers, which is the largest size in the toddler series of clothing that runs from 2T-5T. The T in this size refers to toddlers, which is shorthand for a child who is not fully potty trained. As a rule of thumb, the number corresponds to the childs age, so 5T is theoretically designed to fit an average 5-year-old. However, there is some variation in sizing between different retailers, and some parents may find that size 5 is slightly bigger than size 5T.
