Whether the fabric of a suit is elastic or inelastic depends on the occasion.

First of all, relax.

Chemical fiber suits are low-grade and comfortable to wear, which is more suitable for relaxing occasions. Filaments used for chemical fibers are also slightly elastic. If you want elasticity, you can only add spandex to make the fabric elastic.

If it is a suit for tooling, you can also consider making a suit with a little elastic chemical fiber fabric, which is cheap and easy to take care of.

Second, important social occasions

Wool suits are high-grade, formal suits are more suitable for formal occasions, and wool is inelastic.

If you attend important social occasions, it is more important to customize a woolen suit, which is expensive and troublesome. Generally, woolen suits are best hung for 2-3 days, and must be dry-cleaned when washed.
