Bridesmaid Dresses

So I found this 'inspiration' wedding randomly on a blog and I LOVE their choice of bridesmaid dresses! They essentially have made matching skirts and chosen their own white/ivory blouses to go with them. I don't love the style of skirt, but I love the idea of being able to have different shades of brown and golden tones, with all unique ivory blouses. Then we could add a thicker sash in the same colour to tie all of the girl's together. It would also cover the seem between skirt and dress! I'm just wanting something more unique then the 'off the rack' dresses that are starting to look the same! But at the same time I would hope that these 'make them yourself' dresses wouldn't end up costing a whole lot more!
