Im unable to change anything in slot for Glasses/masks and also shirts.
All I get is an option to change mods on a current gear.

Edit: Found a solution. Unequipped both slots and then I was able to change stuff.

I had a similar issue once I had the "Silverhand" chip installed.
After you wake up and are in bandages, I was unable to change clothes until i removed from inventory the bandage outfit (in the full body slot)

Thanks, this was exactly the information I was looking for.
All my clothes were locked since Johnny was in my head, running around in a pyjama and bandages for quite some time (definitely since 1.04 or even earlier).
All the time I waited for some game progress to unlock these clothes again until I suspected this being a bug (or at least bad game design).
