Is there someone/anyone in the fitting room?
Both of them are ok, right? Pls.
(1) As the moderator told us, both are correct English.
(2) Some people feel that there is a difference in their meaning:
(a) You knock on the door and ask "Is anyone in the dressing room?"
= You simply do not know. You want to know before going inside.
(b) You hear some noise in the dressing room and think that maybe there is a
person inside, so you knock and ask "Is someone in the dressing room?" If there is,
then maybe you will not go inside, for that person may want privacy.
