I bought that storage trunk for my dd for Christmas - It's wrapped and hiding now so I can't really comment on how well it's recieved, but it sure beats the tension rod on a lower shelf of a bookshelf!
We've bought and returned 3 of the Target outfits. 2 outfits simply didn't fit. On one it was the shirt (long sleeve), the sleeves were to tight and when it velcroed in the back it pulled to tight in the front and slid up the belly. On that outfit the skirt and cardigan fit fine. The other outfit it was the jeans that didn't fit - much like the My DIsney Girl outfits I found tucked away in a closet that I bought years and years go from TDS - the jeans wouldn't quite velcro over the behinds of the AG dolls. The third outfit we didn't even attempt, they were all purchased at the same time and we didn't want to chance it. The quality was also umm, well it wasn't awful, but it wasn't great either. It was more $5 quality than $10 quality and it certainly wans't AG quality. None of the shoes for the 2 attempted outfits fit either, they were way to big. The back of one package showed that they had an undergarmet set and that might be worth it.
We bought a shift type night gown, a denim jacket and a pair of lace up converse looking shoes at Micheals and those all fit well enough. The only complaint there is that the laces on the shoes are obnoxiously long.
With regards to matching outfits - my oldest (9) prefers *similar* outfits to outright matching, and my little two who are getting Bitty Twins for Christmas (one twon for each of them) only ooh and ahh over the matching pajamas, they don't seem to care one way or the other about the girl outfits, but they're only 4.
