🧥 Types of Jackets & What Suits Your Shape

1. Blazer

• Best for: Hourglass, rectangular, and pear-shaped bodies

• Choose single-breasted to elongate; double-breasted to balance broad shoulders

• Tailoring defines the waist and flatters bust/hip ratios

2. Biker Jacket

• Ideal for layering over workwear or evening dresses

4. Bomber Jacket

• Best for: Rectangle or pear shapes

• Adds volume to the upper body, balancing hips

• Cropped cuts highlight waistlines—go structured, not slouchy

---

🌍 UK vs USA Jacket Sizing

Jacket sizing is notoriously inconsistent, especially across continents. UK sizes are typically 2 sizes ahead of US labels.
