Sorry, I should have specified. I am building a Shadow Stormtrooper. (AM 2.0 kit with an ATA Bucket)
The CRL for the Legion states, "Belt proper may be made from glossy black ABS or a similar shiny material and must be 3 to 3.5" wide. Black canvas or similar heavy material may also be used." of which material (canvas) I have already purchased from Trooperbay.
From what I have read off posts regarding the "Specialist Program" it has been recommended to have a glossy/shiny belt in place of the dull looking canvas material in order to pull off the over-all glossy look to the kit.
Just looking for suggestions of what material(s) others have used to achieve Specialist.
