Personally, I'm a fan of black leather jackets, and it is one of the things I highly consider before ordering one. The same goes for you. Know your color before you order a custom-made leather jacket.
Did you know that rare colors like white or red are more expensive? Obviously, this would take a longer time to make as they often have to look for that exact shade you want. There are other colors though, black, brown, tan, light brown, etc. Choose a color that goes with what you'd feel most comfortable with and make sure that it would match your outfits.
Black is super versatile and can go with many clothes combinations like white T-shirts and blue jeans. You can also try a mix of black and white in your jacket. Brown jackets give you a trendy rugged hipster look, and it looks great with man buns and thick beards!
How does it fit?
Normally, one would just walk to a store and try out several leather jackets until he finds one that fits them perfectly. For a custom made leather jacket, considering everything is done as per your instructions, knowing your size is the priority. A detailed measurement of your chest and the waist while you're wearing a shirt is very important, remembering that you have to wear something else before you wear the jacket.
You wouldn't want to look like a clown because of large armholes in your coat that gives it an oversized look, or because of having one that the shoulders do not embrace your shape. Imagine going to your workplace with a knee length leather jacket early in the morning! I know, I know, Keanu Reeves looks great in that black leather trenchcoat in The Matrix but those rarely can be passed off by mere mortals.
What type do you want?
Leather jackets come in several design types, and it will do you good to consider the type of jacket you want. There are several types one being the flight jacket that gives you a military edge with flap pockets, turndown collars with cinching waist belts. You could also go with a bomber, which has a front zip and tight cuffs and a turndown collar lined with fur for warmth. Other quintessential styles include the double rider and the moto.
