Does anyone here have experience with the sizing of the Little Adventures princess dresses from mydressuptrunk.com ? I'll be buying for my average sized DD's 4th birthday, so it seems like she should be a size 3-5, but I don't want her to outgrow it too soon. However, I don't want her tripping over the larger size dresses. Are they generously sized? The dress will be for playing at home, not the parks. Thanks in advance!!
