Anyway, modest dress will have folks admiring your clothing instead of your body. For example, you walk past a construction site in New York City. Now, you will hear “Hey baby, nice attire and well accessorized!”
OK, maybe not.
I have pointed out many times on this forum that I’ve gotten harassed in public while in full winter gear.
The idea that clothing is communicative is realistic. That said, there are a lot of things that are more than simply clothing. The basics of a woman’s body shape are going to visible pretty much no matter what she wears. And women are judged much more on this than men are. Not just on overt sexual characteristics - there’s evidence that overweight women are seen as much more inherently lazy and undisciplined than men who are similarly overweight.
There are also other parts of communication. For example, one of the reasons I wear makeup and jewelry and clothing with a certain sort of fit to work is I look older in it. I naturally look like I’m at the oldest college age, if I don’t make much effort, despite being in my early 30’s. I find this detrimental in a professional environment because I want to convey experience and competence that’s in line with my actual age. Part of communicating professional and put-together is clothing that fits in a certain way.
So it’s not a simple case of choosing what to reveal or hide. There are some things that will be visible no matter what. There are others that aren’t simply a matter of showing or hiding - for example, whether one’s clothing is fit to the occasion. That also makes modesty more than about just coverage; there are styles of clothing that are designed for intentional display and styles that are clearly intended for comfort, and one can be more modest than the other while displaying the same amount of skin. Excessive coverage for the situation is also going to send a message.
Also in general, I think historical lines would be more revealing if they didn’t look just at women’s clothes. Many of the different cultural outfits pictured in the end of the video, traditional men’s clothing also consisted in what we’d consider skirts or dresses. The priest’s cassock and monk’s robes are based off of what was standard menswear at the time they were established. Many other garments as well - for example, the sarong in its traditional form and often still now in its homeland is a garment for both men and women. Pants are kind of the historical anomaly in most places in general.
