We have Ikea Pax wardrobes. Dh and I each have 1m of short hanging with a high shelf over, and 4 drawers with the floor 'shelf' under, plus a corner unit with about 60cm of long hanging with a high shelf over and the floor 'shelf' under. Coats and boots are stored elsewhere.
Dh is happy with the amount of clothes storage he has. I'm not. TBH I could easily use the whole double wardrobe! Obviously I will not, but AIBU? How much wardrobe space do you need?
And AIBU to be eyeing up the wardrobe in dc1's room for when he moves out later this year?
