Those look like dress uniforms to my untrained eye. Did you get to keep several sets or did you have to buy new when you wanted them for ceremonial purposes?
We are both wearing our dress blue uniforms.
When we retired we could keep all our uniforms. I kept my dress blues, with an extra white shirt, the bucket hat, purse, dress shoes, boon dockers (work shoes), raincoat with zip-out liner, black gloves, khaki skirt, belt and blouse, khaki hat cover and garrison cap, khaki jacket, all my ribbons and medals, name tag, and extra white hat cover. I got rid of all my other uniforms.
TCS kept his dress blues, white hat, ribbons, medals, name tag and shoes. He didn't want any of the other old uniforms.
Since we would be wearing a uniform only for ceremonies there would be no reason to keep any of our work uniforms--we would never have any occasion for wearing them. The only exception is that I kept my chief's khakis in case I ever got invited to a chiefs' event, such as a chiefs' initiation ceremony.
The rule for retirees wearing uniforms is that they can either wear a uniform that they wore when serving, or they can wear whatever their service is wearing currently, with the appropriate grooming standards. That's why TCS could wear a beard with his uniform--during a period of the 1970's when he served, sailors were allowed to wear full beards.
Some people buy new uniforms if their old ones look shabby or don't fit. Fortunately, mine still looked good and still fit.
The worst uniforms to keep are the summer white dress uniforms. They turn yellow.
wow, 
for sharing that, that is beautiful!
