My favorite thing in the world... classic timeless pieces of clothing that last you LONG. It's the best thing to invest in and for me, it's the easiest way to put together an outfit. Have you ever heard of the Modern French Wardrobe? It's called that because most French woman do just this and only purchase classic pieces that will last them a while. Check out this Pinterest link for a few other fashion ideas of the French. If you can't splurge on quality expensive pieces (which I definitely can't all the time), I go to Forever or H&M, they still have classic pieces at a quarter of the price. I have a classic trench that I bought at Macy's 7 years ago that I still wear. The link is a similar trench. See below for my favorite picks.
