Whether most of you like it or not, women (& men) choose clothing which look good on them. That usually means, it’s “figure flattering.” Yes women are built differently with hips and such, and they are not going to wear bags and robes to cover that up. So don’t get mixed up between “tight” and “fitted” nicely. What I’ve seen where I live, the women usually wear those lycra shirts Under their tops, to keep Within the tznius laws, they are not trying to be flashy. They are made to fit “tight” so the clothing on top don’t look shlumpy, but look refined.
To the person who posted, “pregnant women look like beached whales.” whether it’s a joke to you or not, it’s very insensitive of you to write such a thing. Do you say this before or after you daven for Moshiach to come? Just to clarify it for you, the line is, “I feel like a beached whale,” said the pregnant woman (not an onlooker).
