Recent discovery of Vinted has given me so many jumper problems. I previously thought that four jumpers was a decent god-fearing number to own. Now I am up to six jumpers and counting. Two of them are cashmere. I asked AI and it said that 7-10 jumpers is a reasonable number of jumpers?!? Thrilled if this is so but think this is a situation where I need real human input. How many jumpers do you own?? Bonus points for telling me about your favourite jumpers.
