Churches: Skirts AT the knee OR below the knee? Scarves?

Knees and shoulders need to be covered -both men and women
Doesn’t matter how you accomplish that
Pants , capris , mid calf skirt or dress, scarf

Basilica San Marco is especially strict- no large purses or knapsacks allowed either

I wore whatever ( but not tank tops always with a short sleeve ) and just tied a large gauzy shawl ) cotton gauzy sarong which I doubled as a beach cover up mor towel ) to my purse ( too hot to wear ) and when entering
Churches I would tie it around my waist sarong style , it would go below knees . Never got stopped ( and I’ve been t ice and visited St. Paul’s and Vatican etc ( where they are strict )

Never noted wrinkles being and an issue . Easy to wash in bathroom sinks and hang to dry .

It’s too hot to worry about it honestly .

As for dresses , I wore ones that came to knees and just covered them .

The rule is --- covered knees and no bare shoulders. AND it is interpreted by whoever is at the door. If the knee is always covered, you have no problem. Anything less will depend. Same for shoulders.

Have you checked the average daily high temps for your travel dates? April and May don't strike me as having sweltering temps where one couldn't wear a short-sleeved shirt and a pair of trousers or capris. I appreciate that climate change has had an impact, but is it worse than I realize? Will it be in the 90s in May?
I'm confused about the "petite length" comment. If you want to cover your knees (and you do, apparently), I should think the longer the better. That said, if you don't wear skirts at home, why would you start wearing them now?
As far as scarves, I agree with the other comment that a sarong makes a good multi-purpose travel piece. Rayon ones are readily available. I have a silk one that I bought at a local shop that has since gone out of business. It weighs very little. I have used it as a scarf, a skirt, a swimsuit coverup, a sheet, a blanket and a bathrobe. I have never given any thought to a scarf being wrinkled.

Here’s a scarf I purchased from Amazon that doesn’t wrinkle:

”GERINLY Scarfs for Women Lightweight Floral Birds Print Cotton Scarves and Wraps for Winter Shawl”. It’s $11.

My advice is to bring clothing that you normally wear. If you don’t wear longer dresses or skirts, then bring pants & capris. No need to buy special clothing or be carrying extra stuff with you. I like to wear some dresses in Europe, but not until it’s warmer weather.

Thanks everyone!
I appreciate your suggestions.
I think the scarf is the way to go for me.
Gratefully,
Mary

If it’s warm, looks like it’s already in the mid 60’s in Venice, capri’s and a short sleeve top have been my uniform for visiting churches in Italy over the last few years.
