A leather jacket should fit snugly but not restrict movement. The shoulders must align perfectly with your natural shoulder line. It should not overhand or pull tight. Many brands, like Marty Supreme Jackets UK, allow you to try the jackets. Remember that your sleeves should end past the wrist bone. This way you can cuff the shirt perfectly. Even the waist size should elevate yor body without any excessive tightness. This way you can layer the jackets with ease. The jacket should close comfortably by zippers or buttons without gaping. This can help you enhance your apperance and confidence.
