We're having FI's 2 adorable cousins as flowers girls, and I'd like them to wear white dresses, and I'm makign bows to tie around their waist from extra material from the BM dresses (pink).  My question is - my dress is ivory, so should they have ivory dresses (meaning they'd probably have to shell out and get an official flower girl dress) or is will regular white look fine (meaning they can just find any cute dress from Macy's or whatever store you buy little kids clothes at)  I know WHITE white veils look weird with an ivory gown, but will WHITE white FG dresses clash, too? 

I want something pretty basic (I want them to be able to use the dresses again) like the below 2.  The top is from Macy's for $50, the bottom is from Alfred Angelo (where the BM dresses are from) and are around $170 (more, I might add, then the BM dresses!!!). 

I'm having an ivory dress and FG will have an ivory dress.  I just keep thinking of my picture with her and what it would look like if she were wearing white vs. ivory.  Sorry, but I just don't think white next to ivory will look as good. 

Have you checked David's Bridal FG dresses?  Here is the one my BG will wear...

It's $79-$99 before any sales (and DB's is ALWAYS having some type of sale). 

Also it looks like a fairly simple style.  I bet you could find a similar pattern, fabric and a seamstress to do it for you for around $50.
