Author: Stylist at TellarDate: 2025

Casual shirts are one of the most versatile pieces in a man’s wardrobe. Whether you’re dressing for a weekend, holiday, or casual Friday, choosing the right shirt can elevate your outfit from ordinary to effortlessly stylish. This guide covers types, styling tips, and where to shop — plus how tellar.co.uk ensures you always get the right size.

1. What Makes a Shirt 'Casual'?

Casual shirts are typically made from softer fabrics, feature relaxed fits, and use patterns, textures, or design details that distinguish them from formal shirts. Common examples include:

  • Oxford shirts – A classic staple that’s great tucked or untucked.
  • Chambray shirts – Lightweight and denim-like, ideal for layering.
  • Flannel shirts – Brushed cotton for cooler months, often with checks or plaids.
  • Cuban collar shirts – Short-sleeved with open collars, perfect for summer.
  • Linen shirts – Breathable, textured, and relaxed.

2. Fit: The Key to Casual Confidence

Casual doesn’t mean baggy or sloppy. Aim for comfort with structure. Key fits include:

  • Regular Fit – Room to move without looking boxy.
  • Slim Fit – Tapered without restricting movement.
  • Relaxed Fit – Great for layering or heatwave-ready comfort.
