Those all look great and it's generous of you to make them available!
These are true words that I think we sometimes forget. Due to the nature of cheap prices, I think we are all guilty of a couple of things: A) holding onto/buying things that are not worn enough to justify at any price; and B) not doing the necessary work to make them wearable. If someone buys a $/€1000 odd jacket, they'll almost certainly see spending $50-100 in alterations as justified in order to have it fit to perfection. However, when you only spend $/€20 on a jacket, spending $/€50-100 seems excessive and makes the piece pointless.
I try to keep in mind how much something will cost in order to be useful and instead of looking at a jacket and thinking "Hey! It's only €20!," I try to think "Okay, when I'm done with it, it will be a €70 jacket." Honestly, it doesn't always stop me, but I make an attempt. Thinking about it, I have a brand new pair of Incotex cords that I bought at Neiman Marcus nearly two month ago. They're still with their tags and unhemmed in my closet.
I also know that I love wearing the things that fit well and go with a lot of things. I often wear a navy jacket/blazer because I love the look and it's fairly easy to put together. I own a few of them and would honestly take a few more. I think I'd (and guess others here) would benefit from focusing on core pieces rather than trying to make things work. I've done it a number of times and there are quite a few things in my closet that will prove that giving advice is far easier than following it.
