Thank you ladies for your responses..

I'm going to go with what fits.. A friend gave me some 18 month old capries and I put them on Adriana yesturday and lets just say they are not capries. lol Here's a picture..
I guess the best way to buy is to get what fits.. If she out grows them in the middle of winter, it would be okay.. It gives me a reason to do some shopping. But my DH always complains when I buy clothes for Adriana.. lol oh well..
Justine - I do like buying shirts at Kmart, but I noticed the shirts tend shrink and fit small.. I do have some pants from there and I like the adjustable wastes.. The jeans I have for Adriana now also have adjustable waste also.. I purchased them at Shopko and I'm surprised on how well they held up.. They look barely used..
