What Defines A Coat
- Coats are generally garments longer than jackets, often mid-thigh or longer and heavier than jackets.
- Tailors distinguish topcoats (lighter, ~18–22 oz) from overcoats (heavier, >22 oz).
The Classic Dress Coat Image
- A platonic dress coat often reaches the knees, has a collar or lapels, and may use raglan (sudden) sleeves.
- Such coats can be single- or double-breasted and represent classic dress styles now less common with declining tailored wear.
Pick Raglan Sleeves For Weather Protection
- Choose a raglan sleeve coat if you need better weather protection and want to button to the neck.
- Prefer raglan over set-in sleeves for preventing water pooling at the shoulder seam despite harder fitting challenges.
