i highly think you look adorable in all of them. and i especially like the blue dress if you decide you want to send it to a new home! ;o)
usually what i do is promise myself a new garment or a new "something" if i'm good and get rid of a lot of stuff. maybe if you decide to sell these, you can use the money to buy a new dress you've been coveting? or a new pair of shoes or a japanese craft book or... can you tell i have a wish list a mile long? ;)
I love the first outfit! And I have the last dress so I guess I must like it, too.
