Help with baby shower dress

Ok so this is our invitation and obviously theme as well.

My aunt is making a corsage in this style, with the colors matching accordingly to our theme

I purchased 2 dresses from Pink Blush before deciding on a theme.

So now I'm torn between which one to wear to the baby shower. I feel like the stripes might take away from the corsage and all the colors going on, but not too sure on the navy one. Any advice is welcome! Also, considering I'll be wearing a corsage, would you do just straight hair or curled hair and with which dress? TIA!!
