justonemorecardi thanks very much for linking to the Daily Connoisseur blog. You have given me a real a-ha moment. The gist of the blog is that she is from California and had a transformational experience as an exchange student in Paris.
We're all heavily influenced by our early experiences and it's reminded me of how my Mum had a similar experience which she would always tell us about. She went from a post-war German farming community to study at the Sorbonne in the early Sixties and lived with a Parisian family. Apart from the more bonkers stuff she went on about (you must never cut a potato with a knife apparently), she drummed into me and my sister that less is more, quality matters and, more importantly in her mind, you can have the most expensive, fancy outfit in the world, but if your hair is dirty, you'll still look a mess.
Whether I like it or not, a lot of these things have stayed with me as well as other elements of a strict European upbringing (I had to curtesy to older people until I was in my early teens, I kid you not). I think it explains why I'm drawn to a streamlined wardrobe and classic, quality clothing. Not sure I actually dress like that yet!
In answer to frugal's question about what to do with your 'excess' clothes, the simple answer is it depends, but be realistic. This is discussed a lot on the minimalist/decluttering threads in Good Housekeeping.
I personally eBay stuff although the returns are mixed. We've eBayed loads of stuff, but it's been with the aim of paying for our holidays. I'm not the sort of person (or broke enough) to bother doing it for just more money to go into my bank account as the amounts aren't huge. I know some people see something they want to buy and then eBay until they have 'saved' the money.
Other good places to sell are Gumtree and local Facebook selling groups. Easier to list and the person comes to collect. It can be good for maternity clothing and formal dressing, especially as the wedding season looms.
But be honest - if it's just going to sit in an eBay pile for six months, do something else. Give it to Women's Aid, charity shop or other charity, e.g. If you have excess work or smart clothing, there are projects supporting people getting back into work who need suits and shoes etc.
The thing you have to get your head round is that you will never get the money or time back that you spent on those items. You have to make your peace with that, which can take a while. If I'm honest, eBay is a slight form of penance for me.
