I think jeans, if they are tight, should be elastic, because they will be more comfortable to wear, unlike inelastic jeans, which are a little hard. But if you want to wear something that is not tight, I think it is better to wear it without elasticity, because if it is elastic, the pants will always be put away, which is not so natural; Especially in summer, it is easy to sweat or get too hot. If you wear tight clothes, you will inevitably feel uncomfortable. If you don't wear tight clothes, it will be more breathable and less hot.
