Whether you’re invited to a daytime garden ceremony or an evening black‑tie reception, the right suit serves a dual purpose: style expression and event-appropriate dressing. Here's a breakdown of core suit types:

  • Classic Wool Two‑Piece

    A single-breasted, notch‑lapel suit in mid-grey or navy. Wool (e.g., Super 100s–120s) offers drape, breathability, and crease resistance—ideal across seasons.

  • Linen Smart‑Casual Suit

    Chosen for its natural fibre breathability, linen suits are perfect for summer weddings. Expect slight texture and natural wrinkling. Blend with viscose or cotton to reduce excessive creasing.

  • Cotton‑Blend Casual Suit

    Lightweight cotton with a small Lycra content (~3%) for stretch. Ideal in spring or fall settings.

  • Tweed or Wool‑Blend Suit

    Optimal for cooler weddings. Tweed has visual texture and insulation—ideal for outdoor or fall occasions.

  • Women’s Trouser Suit or Jumpsuit

    Pant‑suit separations or tailored jumpsuits in neutral tones offer sharp, contemporary alternatives to dresses.


2. 🧪 Fabric Science & Seasonal Suitability

Understanding fabric properties is a game-changer:

Fabric Type

Thread Count / Weight

Seasonal Use

Pros

Cons

Super 100s Wool

80–110 g/m²

Year‑round

Smooth, breathable, wrinkle‑resistant

Higher cost

Linen

110–140 g/m²

Spring–Summer

Lightweight, highly breathable

Prone to wrinkles

Wool‑Blend Tweed

240–300 g/m²

Fall–Winter

Textured, insulates well

Heavier, potentially bulky

Cotton‑Blend Stretch

190–220 g/m²

Spring–Fall

Comfortable, moderately durable

Can lack structure

Key Takeaways: Choose Super 100s for formality and versatility; linen blends for summer; tweed for warmth; cotton blends for everyday comfort.


3. 📏 Precision Fit: Size Measurement Protocol

Achieving an impeccable fit requires five essential body measurements:

  1. Shoulder Width – from one acromion to the other (upper bone points).

  2. Chest – around the fullest part, arms relaxed.

  3. Waist – around your natural waist, just above hips.

  4. Sleeve Length – from shoulder seam to wrist bone.

  5. Jacket Length – from the base of collar to where the jacket ends (typically mid-zipper).

For pants:

  • Waist Circumference, Hip Breadth, and Inseam (crotch to ankle).

  • Compare to brand size charts, allowing a 5 mm tolerance around the shoulders and chest for comfort.

Tellar’s Measurement Protocol

Tellar.co.uk uses a database of over 1,500 brand size charts keyed to these measurements, normalised across UK/US/EU sizes. By entering your measurements or upload a garment profile, Tellar returns exact size matches per brand.

This mitigates the risk of ordering an ill-fitting suit—minimising returns and ensuring tailoring is minimal.

5. 🎯 Styling & Coordination

Color Palette Guidance:

  • Navy/Charcoal – versatile day-to-night suits; pair with white or light pastel shirts.

  • Khaki or Light Grey – ideal for summer ceremonies; pair with white/tan detailing.

  • Winter Tweed – pair with burgundy or olive accessories for depth.

Lapels & Vents: Stick to single-breasted with notch-lapel for universality. Double-breasted adds formality but can suit slim silhouettes. A centre vent ensures sit comfort; side vents offer better drape.

Shirts & Ties:

  • Shirt: Small-spread or cutaway collars (no button-down). Cotton poplin or twill for structure.

  • Tie: Width matching lapel (~7–8 cm); silk for formal events, linen blends for outdoor.

  • Pocket Square: Medium-size linen or silk in solid or subtle patterns.

  • Accessories: Minimal cufflinks and polished dress shoes—Medallion tip brogues or loafers.

Women’s Trousers / Jumpsuit:

  • Opt for tailored crepe or technical stretch fabrics.

  • Complete with lightweight blazer and heeled mules or pointed flats.
