Hi there
we are from the UK and have lived in various places in Asia for the past 8+ years. So, here's our experience for what it's worth...
Before we left the UK. we sorted through and kept our favourite winter clothes and shoes and gave the rest to Oxfam.
Asia is very humid and you normally have less storage space as places are generally smaller here.
We keep our winter things in the guest room and depending on humidity levels, run a dehumidifier.
Leather goods in storage go mouldy... dehumidifer or not...
You will only need the occasional light cardigan here - I keep one in the car for when I go into the cold supermarket and for the shopping malls - cinemas are freezing.
Also we spend holidays in Australia and New Zealand where we always need winter gear and not forgetting trips back home to Europe, even in the Summer...
Hope this helps
