I too thought the overlay top was odd. It should hug the body more. Altering the overtop makes the rest of the top need altering also. I like the colors and how they go with the matching skirt.
Loved the style - but didn't realize the plain gray portion on top was an overlay. It was too baggy and looked funny. Hated that the two pink straps at the shoulder weren't covered so NOT bra friendly in any way. Adorable from the back. Not sure what to do with it - can't walk around backwards all day! Will probably try to alter.
