since I work in and around the cemetery prefession, wear the suit, you need to look as prefessional as possible, wear black suit if possible, white shirt, calm looking tie, be sure your shoes and socks and belt all match.
be sure and bring your resume with you and after the interview, be sure and send a thank you letter back to them, this is the proper order of this to do
if you really want this job and do no hear from them in a week or so, then check back with them
just so they know you are still interested

wear what you'd wear if u were the body in the casket,
oh wait, your getting cremated, don't go nude!!!!

wear the suit, and don't offer the information about having lots of matches.

Dress well, and my only other advice would be to inject some life into your interview

My father in law is in this business and knowing him and his associates I would suggest the full suit & tie. If the worst thing they've got to say about you is that you were overdressed- all the better! Good luck!

It's better to be "over-dressed" than not up to standards. If you get the job, then the dress code for business will be explained to you. Best wishes on the interview.

Wear the same thing you'd wear if it wasn't at a crematorium.

If there's any doubt, wear a suit. In general, wear one level better clothing than they do. I dunno what they wear there, though...

Depends on the type of job, but normally its acceptable as long as you look and act presentable
