I go through mine twice a year once in Spirng once in Winter. Then cart off what is not wanted and in good nick to Vinnies. Been trying to get the wife to engage with this but to no avail, however she has started to realise her draws are overflowing (no smart arse comments thank you:) )
I also do it with books and CD's once a year.
Ps what size are you?
I'm a 48 Euro reg.
My missus is as bad as me. Part of the problem is coming from working class backgrounds; we are genetically conditioned to think 'Oh, no. I paid good money for that and there's still some wear in it'. Tragic!
