Most of people are dressed in business casual. But, it's not obligated.
When I attended services a couple of weeks ago, I noticed that the regulars mostly dressed in sports coats with shirts and ties. Myself, a guest, I just wore a dress shirt and slacks. Looking around, you see people in jeans to suits.

It is dressy for an Episcopal church. Many will he wearing jacket and tie. A collered shirt and slacks are fine. Some, mainly tourists, might be very casual in jeans. Anything is ok, it's a church and all are welcomed.
