I think my reaction when I first saw this party on Simply Sienna's Facebook page was to gasp a little. Although ultimately mom had a baby girl, I love how the color palette and the sweet vintage touches -- there are so many ideas that make this awesome for a boy's or gender neutral baby shower. I also think the onesie on the fabric covered backdrop is adorable. (I want to use the idea in a party in the future, for sure!) Wouldn't this also make a beautiful boys first birthday party?
