We go on holiday next month. All paid for but I need to raise spending money. I've sold quite a lot over the past month (30+ items) and made about £200 
However I am now running out of obvious things to sell. The car needs an MOT & a service before we go away so the money I have made so far has to pay for that. I need to raise about another £100 before we leave.
In your experience, what makes the most money? I have a ball gown/prom/bridesmaid dress with matching handbag, shoes and bolero (would list individually) that could go but a little eBay research seems to suggest they don't go for much.
Any advice grateful received!
