Is it normal to wear tank tops as undershirts?
Yep.Totally normal
Yes, wearing a tank top as an undershirt is completely normal. Some people like the extra layer, while others prefer the feel of a shirt on its own.
Absolutely. Tank tops are a common undershirt choice because they add a light layer without much bulk, and they can help keep sweat off your outer shirt.
Some people find them comfy or useful under dress shirts; others skip undershirts altogether. It mostly comes down to what feels good and works with what you’re wearing.
