Did anyone have Dusty pink / Dusty rose color theme? Where did you guys find your bridesmaid dresses?

Try Lulu's! With this color, not 100% sure, but worth a shot! I think they call it Rusty Rose.

I would order swatches from every website that offers that, pick the one closest to your color, and pick a dress style in that color.

I wore a blush bridesmaid dress from David's Bridal in a wedding recently - it was the Vera Wang for DB line, it was very pretty.

I agree with others about there being tons of variations (each with a different name, depending on the vendor/source), so you'll likely need to order swatches. Another issue to consider is if you want the BMs' dresses to MATCH the tablecloths or blend, but not clash, with the tablecloths. Personally, I think shade variations of a color that blend well together look "richer" and have more depth (especially in something like a reception space the contrast of lighter and darker shades in a color family is beautiful), than when everything is as close as possible to the exact same shade (that can get a bit too "matchy-matchy" for my tastes; you don't necessarily want the BMs to disappear against the tablecloths...). It's a pretty color theme!

Also, daughter wore a DB dress that was "petal," which on her very pale skin definitely looked like a "dusty pink," while on a darker skinned BM it looked like a much brighter pink. The same color might look very different on different people depending on their complexion/hair/etc.
