Yes yes yes ! I’ve been to many parishes where some servers in the summer time were better dressed either for a beach or a dance club.
I would say clothing suitable for work places that have either a business casual or professional code of dress would be suitable for Mass. Clothing more suited for the beach, the pool, dance club, rock concert, playing sports, going to sporting events, etc has no place at Mass no matter if you are serving or not.
Ideally, I’d like to see the following with the warm summer months ahead:
Men – no shorts at all, short sleeved shirts - button down or plain shirt without writing on with or without a collar, khaki/docker pants or dress pants, regular dress/plain shoes, no denim, no sandals of any type, no tennis shoes (unless a health or other reason warrants it - then a dark color like black preferred over white)
Women - no shorts at all, capris that reach the knee region or below, dress/skirt not revealing & reaching the knee caps region at minimum, Shirts / top of dress covers the shoulders at minimum and does not dip more than 2 finger breadths below pit of throat, clothing not tight/revealing, dress sandals okay, flip flops not okay, dress pants or khaki pants, no tennis shoes (unless a health or other reason warrants it - then a dark color like black preferred over white)
