Well...it is really strange. I got Abby a medium (7/8) for the Saints game. It fit her like a glove. I am worried that she may change by December. She never gets bigger, she just gets taller!! So..went back and got her a Large, but it looks SO big. Like, it is swallowing her up. I went to another Target a town over and it was the same thing. I am just going to keep the Large and wait until Dec. to make my decision. I will just dry it a lot to attempt to shrink it!
So, only way to tell is just to try it on her. I noticed they were out of the dress when I went to Target two days ago!! It is just so adorable.
On the same note, I got Abby the same dress in yellow and white for Mardi Gras and LSU games. I got a medium and it was BIG on her

I just think it is kind of cheap and you just never know what you are going to get. I will have to check and see what they have in Claire's size!! I was shopping for Aiden and looked at some of the toddler girl's stuff. It is SOOO cute for Spring!
