OK, I've recently been given a TON of clothse in the next couple sizes for my DS. Mostly they're 4s, 4/5, XS, and S. A few 4T and 3Ts mixed in too. My DS is currently in 3T shirts and 2T pants... and I'm trying to figure out if 4T and 4 are the same size or not. The 4s seem a teensy tinsy bit bigger... but does it really count as a seperate 'size'?? Or is it more like 24 month & 2T where they're more just a classification difference and not so much of a REAL difference... also, where on earth does 5T fit in there, I saw some at Khols yesterday and was totally thrown!!
