Need some uniform help

Im looking to replace my fiancés dress blues for our upcoming wedding. Hes a veteran not active duty. Its going to be a surprise for him. I found the navy exchange online store but it would be really helpful if you guys could help me out with a shopping list.

He was enlisted and not an officer so its a little more complicated trying to find what he needs as im a civilian. I dont want to get him the wrong thing and be embarrassed or embarrass him or get him upset or something. Im wanting this to be special for both of us.

He cherishes what he has of his previous uniform but it doesnt fit him anymore. Not to be morbid but ill probably bury him in this uniform and his favorite gun with him.

Hope you guys can help ms out.
