I have spent more on a book that I collect than I have on clothing however my original wedding dress 50 years ago was probably the most I spent! When I think back, it was ridiculous to wear something once, though I did get it slightly altered and wore it once more after.
Apart from that possibly about $185 on one outfit and even more than that on a pair of shoes.
Clothing was a Trent Nathan summer outfit that I bought for one New Years Eve and ended up not wearing it and it sat in my cupboard for years, unworn!
Nowadays, working in an op shop, there is little that I buy in an ordinary shop as I get first pick at all.
