My 4 month old has huge feet & chunky ankles, so I have to buy her socks in the 6 month range.  These fit her feet length wise but are loose at the ankles, so they slip off easily & look a little disheveled on her.

I only took one star off for this because they are sized for older babies.

Other than that, they are really cute and go with everything because I swear they don't make anything for girls that isn't pink (I hate that).
