We're buying 3T tops (unless they look huge) and 2T pants. DD has a narrow waist and 3s fall right down. 2Ts are still a good length, too. So at least she'll get a lot of wear out of most of her clothes from the waist up.
buy both. If I'm unsure about it, I buy short sleeve in the larger size only if I think I can layer a longsleeve something under it or top it with a cardigan or both. So we have some dresses with leggings that I can layer long sleeve under it... you never know how long winter can last, especially given the mild summer. worried it may be a long winter.
