Abercrombie and Fitch Kids .?

Sounds like I'm around the same as you, Abercrombie Kids t-shirts tend to be fairly short so I usually go for a medium for their tees. I'd say that you should probably get a medium as well, it should fit fairly well I believe. As for fleece, you would probably take a large or medium- it really depends on how tight you like your clothing. I have a couple of fleece sweaters from Abercrombie Kids and I purchased them in large but I definitely could've gone down to a medium... if you prefer things to be tighter I'd go for a medium in fleece as well. As for jeans, I'm 5'4 and take size 14 in Abercrombie Kids and they fit perfect length wise so they'd most likely be to long for you. I'd go with a 12 for jeans =) Best of luck! Hope I've helped.
