Which mens undershirt is right for my needs?
The right undershirt depends on how you wear your dress shirt and your daily requirements. If invisibility is your main goal, focus on color, neckline and flat finishes. If you want better protection against sweat, sleeve shape and moisture absorption become more important.
Material also plays a key role: some fabrics are especially soft, others manage moisture better or remain more discreet under a shirt thanks to smooth surfaces and flat edges.
Close-fitting undershirts in beige or natural tones are often particularly discreet. For open collars, a V-neck or deep V-neck is usually the best choice, while a crew neck works best when wearing a tie.
