I have found there is a very strange phenomenon between size 6X and size 7/8. It seems clothes suddenly jump from cute to "tweeny" with Justin Bieber or Hannah Montana all over them, or covered with rhinestones and lots of black, etc. Personally I hate that stuff! I don't want my 7 year old looking like she walked out of an 80s video. And she barely even knows who Justin Bieber is and she hasn't seen Twilight (nor do I want Edward Cullen on her pajamas!). I know there is Gymboree, but at times it can be a little TOO young/sweet. I just want cute and simple. Well, mermaids and seahorses (a huge favorite of hers) are good too. ;)
Am I just looking in the wrong places? For example, she had a very specific request of either mermaid pajamas or a mermaid bathing suit (but NOT Disney Little Mermaid) for Christmas. (There is a long back story to this, but suffice to say she has a fondness for the sea!). I couldn't find them anywhere....every super-cute thing I found ended at size 6X. Then it moved into the bikinis, etc for "tweens".
I feel like there is a big gap in clothes for kids about sizes 7 - 10, unless I'm just totally missing it.
