needing a peek-a-boo slip

amongthelilies25

So..my colors are red, black, and white. 
my BMs are wearing little black dresses...and the mother of my FG picked this dress out and ordered it. 



at first i was thinking this would be too much black..but now i think it will work with the right splashes of color. 
i was thinking maybe i could buy a red peek-a-boo slip thing for her to wear underneath....what do you think? and she'll have a red headband..and holding a white basket with red ribbom. 
what do you girls think?
and where can i find a red peek-a-boo slip?
