I have just sold 4 Rapha shirts on eBay (2 short and 2 long sleeved) that I bought on sale over the last couple of years.
£92, £80, £80 and £42 !!
I am pretty sure that is more than I paid for them and I can get some new ones that fit plus some other things I need with the proceeds. I sold them because they don't fit since I started lifting weights at cross fit so they are gratifyingly too tight around the chest, but not the gut.
