wear ordinary business dress for your location and climate, whatever you would wear say for a job interview or important meeting, as this occasion is Very Important. I would not recommend a suit here as it will be over 90 on Saturday, and the church is never cool even with the AC blasting. dress shirt (no tee, no message), slacks or trousers, shoes and socks. if you need a jacket for the weather, wear one.

For some of the older generation “dress clothes” in Texas means brand new jeans, white shirt, stetson (removed at the door), boots, belt buckle and bolo tie. dress clothes for Winter Texans seems to be golf attire (no spikes). at first I read “pink skirt” in OP but re-read it and conclude you are a gentleman. there is a forum-ite (and we have a parishioner) who wear kilts, authentic tartan for their clans. the good thing about wearing a suit is you always feel properly dressed, and that in itself can ease anxiety (at last it works that way for ladies).
