Having been processing my thoughts for a good while, I feel confident enough to share a few tips, so in order to achieve a refined and functional wardrobe:
Analyze your wardrobe:
Think of how you want to dress, go through your wardrobe and fill its needs. I try consider what would work within my own wardrobe and how to build on my style. It is so important to give some thought to your style and wardrobe in order to avoid wardrobe crisis!
Quality over quantity:
I believe in being selective and I apply that theory to all aspects of life. As Ilona Hamer has put it: "you need very little to put a look together, but you need the right pieces." Harsh but true, so I would suggest to buy less and choose well. Once you have stocked up on the perfect jacket, jeans and shoes, you might realize you don't need something new all the time.
Find your brands:
Only buy from brands which share your values and you identify with. I love feeling proud of what I wear, and this ways it is easier to stay selective and true to your style. I stick to the brands which inspire me the most, such as Céline, Toteme and hopefully soon The Row, unless something 'to die for' comes my way.
You should feel comfortable in what you wear. I strongly believe that wearing the right clothes makes me feel confident, and most importantly, I want feel 'me' in my clothes. I call this one the social benefit card - other people will notice the difference.
Trust your instincts:
Otherwise everything goes wrong! It is not about following trends, instead you should buy and wear what appeals to you.
