Just being nosey really 
I've got a friend who recently lost a jacket she's had for years and loves, and it got me thinking about what items I love more than any others. I have 2: a pair of tan court shoes that I wear all the time as they just go with anything, and a beautiful floaty top that I've worn many times to special events including my best friend's wedding and on the night I got engaged. Both just really suit me and I'd hate to ever have to try and replace them!
What items do you treasure the most in your wardrobe?
