What do Muslim women wear to swim?
Bad ads is embarrassing

The Muslim women here wear jeans, t-shirts and headgear. It's funny because the wet t-shirts are a bit sexy.

Women from different countries do not dress and behave the same.
The ad posted by OP shows a woman wearing a bikini. This is considered unacceptable in Muslim countries such as Bangladesh.
Women in Europe/North and South Americas/Australia enjoy much more freedom compared to women in other parts of the world. This is something we should all understand.
We all know this.
The guy with a lack of knowledge is the OP who believes that a US/international site will have to conform to Bangladeshian social norms.
That's why we're making fun of him - in a friendly way.

I am not talking about religious restrictions, the fact is in this south asian region, people in every country show respect to the values in our society. we grew like that. Now think when your elder/younger relative or respectable person watches that a woman wearing appealing bikinis( i mean it, look the pic i showed) it's embarrassing moment, isn't it?. For instance, they may say - "Mridul what r u doing, you watching porno, shhh you watching a girl wearing panty!...." . I can imagine it's true in all countries not only here. So please stop abusing and leave it.
Uhhh
I know.
