#1 is on sale in stores, nothing special... the neckline (v-neck plus ruching at shoulders) bothers me for some reason, and it kinda makes you look preggo
#2 is cute, but just tee shirt material, and iirc, it is expensive for t shirt material
havent seen #3
#4 is really great if it fits right, but is a stretchy, spandexy material on the bottom so hides nothing.
