That's a good idea. Thank you. I'll write it down to offer as a suggestion when I meet with him next week.

One doesn’t genuflect to the altar. It isn’t appropriate. (Nor is it appropriate for women to wear clerical garb. I say this as a woman.) Genuflection is reserved for the Blessed Sacrament and the crucifix on Good Friday.

One thing to be conscious about is that even if one’s dress/skirt is “appropriate length”, bending, bowing, etc will cause the back to ride up (depending on one’s build and if the dress hasn’t been altered accordingly, the back hemline will already be shorter than the front), to the point of indecent depending on the length. (and I’ve learned the hard way, don’t trust a saleswoman to give you honest feedback about this in the store before you buy it. They lie. Thankfully I was able to return the dress when my mom came to do alterations and informed me of the issue.)

What I suggest is bowing as you should, but approach at a slight angle so your backside isn’t directly in front of the camera. Mention your concern and see if you can experiment early beforehand to find the most flattering way of doing this.

Also, be wary of your neckline when bowing. I hate cowl/draped necklines.

I suppose I was considering that a tabernacle being centered, one could genuflect,
but I guess you may be right that the bow at this point in the NO is to reverence the altar (especially since many don't have their tabernacle where it belongs).

There is also a difference between bowing and bending over.
All of these things may still need prior practice, so that any decision isn't awkward.

My psalms are always sung from the loft, but they can be sung from anywhere in the building if necessary. I wouldn't lose sleep over this.

Skirt tip mostly relevant in warmer climates - use not only a skirt that is at least below the knees, but also one that is made of a sturdy and thick fabric, not stretch-gymnastics fabrics, nor very light, thin rayons. Traditional skirts had slips or linings for a reason. :)

One can also bow with the head and shoulders, without bending at the waist. Or do a schoolgirl curtsey - just tip one foot back, bend the knees a little, and bow the head. A full genuflection can be really difficult for older people, arthritic people, fat people, and women in fitted skirts (like business-suit skirts). :)

Tea-length skirts/dresses are ideal, but are difficult to come across. Dresses, I find, are either the right length, but immodest up top, or modest up top, but too short below.

When it comes to modesty, it really does depend on how a woman is built. There are plenty of things women of a non-busty and non-curvy (and I mean in the correct sense of the term, not merely as a euphemism for being overweight, though one can be both, as I am) can get away with wearing that I could never wear. Dress for your body type, and before buying, bend, move, sit, etc as you would to test how things will fit. Also, don’t underestimate what a good seamstress can do to make something that isn’t quite modest become modest. Finally, ever woman should have a nice collection of cardigans and boleros.

About this whole bowing thing.....

How can people claim that there are no substantial differences between the EF and the OF, when one is full of genuflections, and everyone who passes by the altar genuflects, reflexively, while genuflection in the OF is (putting it very politely) uncommon, and proscribed in the rubrics in some places?

Bowing vs. genuflecting vs. pizzicato?

Thank you all for your input. We resolved this by simply keeping me at the lectern. It was easiest for all involved, including the cameraman.

My dress was thick black floor-length cotton with a modest round neckline - about as distraction-less as any clothing gets. I've found eshakti to be a good source for modest dresses, because they allow you to customize measurements, neckline, skirt length, and sleeve length, and it doesn't cost any more than buying something at a department store.

I'll be grateful when we settle into the new normal and the cantors are back in the choir loft. I am not enjoying the production Mass has of necessity become in the short-term; it's so stressful that I can't in good conscience subject my non-musician cantors to the ordeal (they're already challenged by a normal Mass), so I'm all we've got until the new sound system is fully functional and integrated into the new camera system.

We're going to come out of this with some pretty good stories though!
