Where to buy clothes for preemies?

My baby is not a preemie she was born at 38 weeks, 5 days, very healthy but weighs 4lbs 13oz and none of her clothes that I bought fit her. Her gloves 2 keep her from scratching herself fall out right when I put them on, all her socks are 2 big even the smallest new born outfit I have 4 her drowns her. On top of that the hospital gave me a bag of pampers that say for preemies but I have 2 cut them and tuck them bc they are just 2 big. Is there a department store that sells a wide variety of clothes 4 preemies so I can at least buy her alittle bit of well fitting clothes and gloves so that she doesnt keep scratching herself and has 2 be wrapped up in a blanket all the time? Thanks. I've tried 2 walmarts and was unable 2 find anything...
