Prepared Sleeves Buttons are not attached, button holes have not been completed. A tailor would perform final measurements of your arms and finalize your jacket. This option provides the greatest accuracy in fit though the jacket should not be worn until the tailor has completed their work.
Completed Sleeves Buttons are attached and button holes are completed. The garment is completed and tailoring is not necessary. This option is NOT recommended as the other two options provide the most accurate fit.
Over Prepared Sleeves This option is similar to Prepared Sleeves but the buttons have been temporarily attached so that the jacket can be worn immediately after arrival. This option is recommended though the jacket will still need to be taken to a tailor for finishing.
