We actually got fitted at Carolyn Allen's during our planning session visit, and found them to be a little rude. We ended upgoing with After Hours Conventions and they were WONDERFUL! We worked with Linda DeMarco, and she was so nice and helpful.
They delivered all of our tuxes to our hotel 2 days prior to the wedding for the fittings, and picked up DH's tux 2 days after the wedding at our BW garden suite when we finished our MK Photos.
She communicated well via email and was actually slightly less expensive than CA's. But if you also need your dress steamed, I would go with CA's. I didn't need to do that.
Of course, this was over a year ago, so things might have changed.
