Suit jackets are commonly single-breasted with two or three buttons, and some are double-breasted with four or six buttons. They are also the most fitted option and should not be layered. You should only wear a shirt underneath to fit perfectly.

2. The shoulders

Suit jacket shoulders are hand-made, giving them a rounded, well-defined, and structured look. They are also heavily padded, giving the jacket a more formal and classical feel.

Blazer shoulders are tailored using the same technique as shirts, giving them a softer look and following the natural shape of the shoulders. A blazer embodies sophistication and is a go-to choice to elevate your style without being formal.

3. The inside

For a suit jacket, the inside is tailored using the interfacing technique, which ensures softness and tightness. Go for a well-fitted jacket, as it sets the foundation for the entire outfit.

4. Fabrics

Suit jacket fabric must be sturdy, tear and abrasion-resistant since the trousers will be cut from the same material. The rule is only to wear them together, or they could become washed and lose colour if you wear them separately.

For a blazer, the fabric can be lighter, less sturdy or in different patterns as it differs from the trousers. A blazer is a timeless piece that can adapt to various occasions, making it a must-have in every man's wardrobe.

5. The fit

A suit jacket is made to fit closely to the body. It should not also be worn with multiple layers underneath.

Blazers have a loose fit and are not structured in the shoulder area. A blazer of Italian heritage has a looser and more relaxed build.
