Yep, it does. You probably seen it irl and just didn’t pay attention.

It’s pretty well drawn. You can also see the clothes sagging more near the waistlines where it stretches less. (Both are probably wearing similar fabrics for their tops).

This artist has a solid skill level, if they meant to make baggy clothes or a different type of fabric it wouldn’t be a problem.

Google any tube top tanks or stretch tube tops and I’m sure you will get similar examples from photos.
