T-shirts

I like the convenience of wearing a long sleeve t-shirt. It does not require layering which is great for a hot day. But women's t-shirts are often low cut, boat neck, or tight on the chest so they require adjustment for hijab. Men's t-shirts are so much more modest--just compare the neck of this men's t-shirt to the neck of the women's tees! And of course a man's tee is looser in fit. I know some Muslims might say women should not wear men's clothes, but I think it is fine as long as the intention is to be more modest and NOT to look like a man. What do you think?

There are products such as arm covers that women can use to extend the sleeve length.

Also, there are products called "dickies," that one can use to cover the neck and chest. Dickies are worn under the shirt and do not cover the whole torso, just the neck area:
