Discover men’s cotton T-shirts at Peter Jackson, with the Girolamo crewneck offering a considered foundation in white, navy, brown and black. A smooth mercerised finish and substantial cotton handle give these tees a more defined surface for relaxed outfits and layering.

Cotton with a clean, structured feel

The current Girolamo range uses 100% cotton in a substantial 225gsm weight, with short sleeves and a classic crew neckline. Mercerisation gives the fabric a refined surface and subtle lustre. The result offers a different feel from a lighter casual tee, so consider the garment weight as well as fibre when choosing for the weather.

Build simple combinations with texture

Pair a plain tee with jeans or chinos, then introduce a casual jacket for another layer. A suitable sport jacket can create a more considered smart casual outfit where the dress code allows. Compare polo shirts when you want a collared alternative.

T-Shirts FAQs

What is a mercerised cotton T-shirt?

It is a cotton tee made with fabric treated through a finishing process that can enhance the surface, colour depth and lustre. Check the product’s own fabric and care details for the specific garment.

Can a T-shirt be worn under a blazer?

A clean, well-fitting tee can work with a suitable blazer in a smart casual setting. A substantial or smoother cotton finish gives a different effect from a very relaxed jersey. More formal dress codes may require a collared shirt.

How does T-shirt weight affect layering and comfort?

A more substantial fabric can give a defined silhouette and a different drape from a lightweight tee. It can also affect how much space the garment needs beneath a jacket. Compare the actual weight, construction and conditions instead of choosing for warm weather from cotton content alone.

What should I wear with a plain tee for smart casual occasions?

Compatible chinos and restrained shoes can give a plain tee a considered setting; a suitable jacket adds another layer where appropriate. Check the venue’s expectations before choosing the neckline. Use polo shirts if you want a collared alternative within a relaxed outfit.

How should a T-shirt fit at the shoulders and hem?

The shoulder and sleeve should allow movement without excessive fabric, and the hem should work with the intended trousers. Try sitting and raising your arms to assess length and comfort. A close fit should not rely on pulling across the chest, particularly when layering beneath a jacket.

Can a mercerised cotton tee use the same care routine as every cotton top?

Use its own label rather than a universal cotton routine. Finish, colour and construction can affect washing and drying guidance. Mercerisation describes a fabric treatment, not a guarantee against shrinkage, colour change or damage from unsuitable heat. Follow the stated instructions to preserve the intended surface.
