What stores have dressing rooms open?

I went last month to get my son a suit for graduation and no dressing room was open. However, if it doesn't fit they will accept the return. They were very gracious about it too. They know the inconvenience. What I did was have him try the shirt in the car. I live in Bartow, so I'm not down the street. We had looked everywhere for this particular outfit. We ended getting the pants at Burlington by Wesley Chapel and they too had their dressing room clothes. But my brother's place of work us near by and we used the restroom to check and see if the pants fit. And they too were willing to have the clothes return if it did not fit.

Most larger department stores & a few smaller ones.
