I have faced a similar issue in 1.04, but came across a solution to my case: the inventory box of your clothing does occasionally not adjust in size and thus hides the stowed item in an unaccessible area (still blocking the slots, and technically still being in your inventory).
My working solution was dropping the respective clothing (e.g. pants or jacket) and the putting it back on. Afterwards the box size was readjusted and I could access the items as normal.
