I might have an opportunity to attend my first Tridentine Mass this weekend (maybe, hopefully–cross your fingers for me!). But I am very nervous. I have a couple issues, mostly about what to wear. They are:
1.) Communion. I’ve never received Communion on the tongue before, or at a kneeling rail, so I’m nervous about that. I’m not used to sticking my tongue out at people.

What if I drop it?

I’d hate to go a week without Communion if I don’t have to, but would it be wisest to not receive it and just observe and take mental notes for next time? Am I overthinking this?
**You think you are more likely to drop it if it is placed directly on your tongue than when it is first manhandled by a layperson and placed in your palm?? There’s always an altar boy holding a paten under your chin to catch the Host if it drops, which rarely happens anyway. Simply tilt your head back, open your mouth, stick out your tongue a little, then when the priest puts the Host on your tongue, close your mouth and let it disintegrate in your mouth with your saliva before swallowing it (don’t chew it!). **
2.) Following along in my missal. I have the 1962 one from Angelus Press, but I’m still wary of not really being able to follow along. I think I can manage, though. Will the readings or homily be done in English, or Latin? Does that depend on the parish? If I don’t give responses, because I don’t know how to pronounce Latin words, would it be all right to just be quiet?
Most traditional priests give sermons, not homilies; there’s a difference. In any case, it is always in the vernacular (English). The readings are done in Latin at the altar, and then read in English from the pulpit just before the sermon. Following along in your missal will take some getting used to…remember, you never know where exactly the priest is at except when the bells ring, and while the choir is singing the “Sanctus” the priest is probably already about to perform the Consecration. Just relax, read through your Missal, adore the Host and Chalice during the Elevation, and include some private devotional prayers of your own before and after communion–the Angelus Press missal has some great ones to choose from.
3.) Clothes. I’m really worried about offending people when it comes to this, since I’d really like to keep going to this parish for awhile. I don’t want to be known as that girl who came in dressed all wrong and was too embarrassed to come back.
For example, would this outfit be okay? I am short, so the dress comes to my knees. And don’t worry, I would also wear a black sweater over it that comes to my elbows, plus this mantilla I bought awhile ago but haven’t had the chance to use yet.

Or would calves and forearms be showing too much skin? Should I keep looking for Mass-friendly clothes? (And where in the world do you gals find those!?)
**It’s a Mass, not a cocktail party. But the dress probably wouldn’t be a problem IF you are going to wear the sweater over it. Showing calves/forearms is fine. As long as your dress reaches below the knees and there is no shoulder, back, or cleavage exposure, you’ll be fine. **
4.) Is there anything else someone born and raised in an NO setting should know before going to a TLM? Anything in terms of etiquette or relating to the Mass? Did anyone here switch over to the EF like I am hoping to? What helps you get the most out of it?
There are a lot of differences, and for someone from the NO it will take some getting used to. I think if you keep in mind that the participation in the TLM is active, but a contemplative, meditative sort of active rather than mindlessly repeating phrases at the priest or layperson’s cue as in the Novus Ordo. In the TLM you are a lot less conscious of yourself and the people around you. Your focus is on the priest’s actions at the altar, and on the Sacrifice of Jesus Christ at Calvary made present before your eyes.
This was über long. Perhaps too long. If you got through all this without virtually slapping me, kudos to you!
