@bjhess I don't actually have one! Half of my clothing is always stored in vacuum bags on top of the wardrobe. Small London apartment requires this!

So before I unpack it (e.g. winter clothes), I place all my clothes from the wardrobe (e.g. summer clothes) on the bed and walk through them piece by piece. They go to recycling if they no longer fit, if they're worn beyond repair or if I've not worn them once.

And when I unpack the vacuum packed stuff, I repeat before hanging anything up or putting stuff in drawers.
