Why do girls wear undershirts?

Girls and women wear undershirts for various reasons, including:

Comfort: Undershirts can provide an additional layer of comfort by regulating body temperature, providing extra warmth in colder weather or absorbing sweat during physical activity.

Modesty: Undershirts can help ensure that certain clothing items, such as sheer blouses or low-cut tops, maintain a level of modesty and coverage under the outer layer.

Coverage: Similar to modesty, undershirts can add an extra layer of coverage to help with any potential exposure or visible bra straps.

Layering: Undershirts serve as a practical layering piece, offering additional warmth or the option to adjust layers as needed without having to change the entire outfit.

Smoothness: Undershirts can create a smoother silhouette under certain types of clothing, minimizing visible lines or contours of undergarments.

Support: Some undershirts may provide light shaping and support, helping to enhance the fit of certain clothing items or provide additional bust coverage.
