a hoarder wouldn't keep it clean and organized.
From wikepedia: Compulsive hoarding impairs mobility and interferes with basic activities, including
cooking,
cleaning,
hygiene,
sanitation, and
sleeping.
If your clothes keeping is not causing any of the above..then I really would just call it compulsive shopping..and maybe a bit of pack rat. It may turn into hoarding...if you get to the point where it's no longer neat/tidy or is causing any of the above.
For things that are brand new, still with tags, But your not going to wear them...I would suggest try cosigning them at a shop, on craigs list or even ebay....instead of good will. That way you won't feel like your throwing them away. Look up the brand name and style on ebay and see what you find. You might be surprised.
The reason I'm a stickler about not calling non hoarding...hoarding..is I've had to clean up actual hoarding..and no way on earth is it the same
someone who just likes to buys clothing or knick knacks ect and keeps them clean, dirt free, clutter free and organized isn't a hoarder. They throw away trash, they don't keep complete junk, and cleaning out this kind of home is not completely disgusting (I know I've done this before!)
Me having to get rid of feces covered crap, trash piled up to the ceiling, finding dead animals, findings rotting food from years ago, heck we even uncovered dynamite (dead FIL)..no joke it's so different. Don't burden yourself with the hoarding name unless your truly a hoarder.
Your sounding a bit compulsive clothes shopping. And a bit pack rat. My rule is I buy an outfit or shirt..I get rid of one. One comes in, one must come out.
