Scrub suit vs white, crisp clinical uniform with nurse's cap?

The hospital where I work is being ran by nuns as administrators. We Nurses are expected to be conservative and sort of traditional in carrying ourselves. We still wear cap, hair neatly tied up in a bun with hair net, white leather duty shoes, but 4 years ago, wearing pants for women has been approved.
Lately, the employees union has proposed nurses to wear scrub suits and rubber shoes for comfort and for many other reasons.
More senior/older nurses are refusing for the change in uniform because they say that traditional nursing will always be integral in embracing modern times. They want to preserve the identity of nursing being the only profession with white uniform and cap; and they say Nurses are more dignified, respectable, and noble in white, crisp uniform than in scrub suit.
Do they make sense? I mean, that was a thing during the era of military nursing corps! Wearing scrubs I think is more convenient, practical, fashionable, and its colors are even less threatening to pedia and pschiatric patients.
Anyway, I don't think I also make sense, do I? Hehe
