Capes and children

[ButterPie]

OK, so for an August wedding in a theatre, adult bridesmaids wearing www.fashionunion.co.uk/p/LDR1030/Rosa-Sundress.html, groom apparently dressing like bryon, bride wearing lh4.ggpht.com/_cyCNjVH0Zd8/S8N54lvWY_I/AAAAAAAAA0E/h5evuYrbzHA/73eabf02.jpg and a garland and bouquet of handmade cloth flowers, yet to be made.

I want a cape. A big, dramatic cape. With a hood. What type should I go for? Velvet? Organza? What colour?

Also, I have a 9mo and 3.5yo as child bridesmaids, what should they wear?

This is all to be done on a tight budget btw.
