Popa: Don’t judge a woman’s need to feel fashionable and attractive under the constraints of tsniyus.
It’s really hard to be tsiniyus and feel fashionable- so if this is one way to help women feel halachically tsiniyus and good about themselves, please don’t judge them. Even if you happen not to approve of denim skirts or whatever.
And just FYI- there are plenty of denim skirts that are not tight, form fitting or too short.
To each their own…
