We had this discussion before on other threads. Many and I will say it again because “many” of us disagree but “MANY” women “dress to impress” other women. And the concept of “dressing to kill” is that the other women should c”v drop dead when they seem them. lol.
On the other hand there are many women who have no clue, absolutely without a shadow of a doubt, that they look to put it mildly “over the top” in many cases they don’t even realize how borderline or questionable their tznius level is. They look away, make an excuse or whatever. Others as one said just look to see how their elbows, knees and neckline is covered and not in what way.
And that goes for makeup as well. The idea of makeup is to have it enhance your natural beauty. Anyone with any degree of “class” does not slather on makeup or have it stand out like a marquee flashing “look at me”. When they look in the mirror they think they look good. When we look at them we don’t even see them, we see ruby red lipstick, false eyelashes, blue eyeshadow and lots and lost of mascara and maybe even hairspray. It might not be that non-tznius if we don’t really notice or recognize the person beneath it all.
