Though there are exceptions! I keep itching to purge my closet of unworn items, but I was pregnant and then breastfeeding for the last year. I keep having to remind myself that I will get back to my regular clothes in a few more months, and then it will be the maternity/nursing clothes that need to go. Since it sounds like OP doesn't get to wear any of these clothes very often, there may be plenty of stuff that hasn't been worn in a year but is still worth keeping.
