Depends on the garment and if it runs big or small. She's been in 2T shirts for a while, but I bought some 18 mo. pants because 2T were just huge and 24 mo. fell off her no-butt. If the pants are too long, she spends more time pulling on them than playing. I do have 3 and 4 T things set aside in her closet. I am more likely to buy pants at her size and shirts/dresses/pjs slightly bigger. I will also buy shoes if I see the same ones we like on sale in bigger sizes. I know she'll get to them eventually. She always needs sneakers.
