Posting personal UK bought clothes to UK from abroad

I'm on holiday abroad and would like to post some of my luggage back to the UK. This includes a suit that I bought in the UK about 9 years ago and no longer have any proof of purchase for. I took it out of the UK in my Hold Luggage on an airplane, and now want to post it back using POS Malaysia. How do I correctly declare the goods as personal items being returned to the UK? Do I just write "Returned goods — relief claimed" on the package and ask the Courier to add it to their forms too? And do I need to worry about the value of these items?

Hi,
The criteria and process on how to claim returned goods relief is explained in  the link below

Thank you.
