Bridesmaid dresses other than David’s Bridal

Hi! Looking for suggestions on bridal stores for my bridesmaids as we are coming up on our deadline soon. I know there’s a ton of online stores out there (which I’m not totally opposed to however I know this can be dangerous if you really don’t know you size or store). I was hoping to find another universal bridal shop like David’s Bridal that my bridesmaids could go to try on their dresses - as they all live in different cities/states. Thanks! (Nothing against David’s Bridal I just haven’t really found any dresses there that I’m in love with).

Also, would coordinating “mixed and matched” dresses be too difficult to do? My one bridesmaid asked if colors cross over to different shops and I said I would have assumed no as they all carry their own colors.
