• UK/US Men’s Shirts: Usually measured by collar size in inches (e.g., 15", 16").

• Fit terminology differs:

  • UK: "Regular", "Slim", "Tailored"

  • US: "Classic Fit", "Fitted", "Modern Fit"

Best Shirt Materials for Style and Comfort

Which Shirt Fits Which Body Shape?

For Women:

• Petite: Opt for cropped or fitted shirts that don't drown the frame. Avoid oversized styles unless styled with structure.

• Curvy/Hourglass: Choose soft, fluid materials like silk or viscose that follow the body line. Wrap styles or shaped seams help enhance the waist.

• Athletic/Rectangle: Oversized or structured shirts add dimension. Look for pleats, patterns, or breast pockets to build shape.

• Pear-Shaped: Light colours and shoulder details draw the eye upward. Try structured shirts tucked into darker bottoms.

For Men:

• Tall & Slim: Slim or tailored shirts avoid excess bulk. Avoid ultra-skinny fits that highlight narrowness.

• Muscular/Athletic: Stretch-cotton blends accommodate shoulder and chest without gaping. “Athletic Fit” or “Tailored Fit” styles work well.

• Stockier Builds: Regular or Classic fits avoid clinging. Vertical stripes or darker shades streamline the silhouette.

Styling Advice: Shirt Outfits for Every Occasion

• Workwear: Cotton poplin, crisp collars, and tailored fits. Pair with blazers or high-waist trousers.

• Evening: Silk shirt tucked into tailored trousers or a midi skirt. Add statement earrings or heels.

• Layering Base: Button-down under jumpers or sweater vests in colder months. Try shirts with interesting collars or textures.
