I don't expect knits to last all that long, no matter what the price or brand, and how well I baby them, which I do. I can get one year out of them for looking nice, then the following year they are relegated to layering only, beach wear, then the year after that they may make it into sleepwear and lounge capsule.
Summer clothes have the shortest life of all -- sweat & sunscreen, more frequent laundering, sand from the beach, etc. I am hardest by far on my summer clothes. I also do not invest a lot of $ in my summer clothes, because I know I'm going to have to replace 80% of it the following year.
Then there are the miracle knits I find sometimes that are seemingly indestructible. For example inexpensive camisoles from H&M I purchased years ago. I wear these very frequently and do not baby them at all, frying them in the dryer, etc.... and they continue to hold up year after year with no fading.
Wovens seem to last a lot longer which is why I prefer them. I tend to grow bored of them, or grow out of them, before they wear out. I am more apt to stain a woven top accidentally. Or a top has to go because of pit stains. Or a woven starts to shine because of ill treatment by the dry cleaners. I have had a lot of clothes bite the dust after a trip to the dry cleaners, unfortunately.
Sweaters: can be all over the map. I have sweaters that are 10+ years old. Then I have sweaters that *should* have lasted years, but started looking shabby after just one. I do think sweater quality has gone way down in recent years -- even the better brands.
Jeans: I haven't blown out the knees on a pair of jeans since high school. Then again, I don't like to wear jeans all that often.
Coats: I own a lot, because I live in a colder climate. I have many that are several years old and still look as good as new. Often what happens with coats is that I'll lose a button or break a zipper or the lining will tear. These things can usually be fixed. However mostly what happens with coats is that I buy one that will "do" -- not perfect but close enough -- and it gets replaced when I find one that is perfect. My Bernardo puffer, which I love, is probably not going to last too long, because it sheds feathers like crazy. White or cream coats are prone to staining, or showing wear on the cuffs. With coats I always wear a scarf around the neck, to prevent ring around the collar.
Shoes: I baby my shoes, especially the ones I've spent a lot of $ on. If they are comfortable favorites that fall out of fashion I have been known to tuck them away until they come back into fashion. Believe it or not, I have Me-Too ballet flats that are still going strong. My tall boots are all 5+ years and still going strong. I do not ever wear my suede boots/shoes if there is any hint of rain or snow in the weather, or salt on the ground. I wipe off my boots immediately when I get home, so salt doesn't sit. I take my shoes in frequently for cobbler TLC. I rotate so that shoes have a chance to breathe. And I wear socks whenever feasible -- because I find it is the shoes you can't wear socks with that wear out the fastest.
I had a pair of sandals, worn daily in the hot months, that lasted 4 years. I only just discarded them. I never wore them on the beach, because sand is so hard on sandals. I have two pairs of Jcrew thongs. The silver pair is oldest, and starting to look ratty, so it is reserved for the beach. The gold pair is newer and is reserved for wearing anywhere but the beach. If a particular shoe works really well, I duplicate so that I can rotate. Such as the Jcrew sandals, but also including athletic sneakers, and Me-Too ballet flats, and my favorite booties (which I have in black, blue suede, and leopard).
I choose wedge shoes instead of heels if I'm going to be walking on cobble stones or grass. If I'm driving I will wear a different pair of shoes to save the back of my better heels from getting scuffed. I carefully pack my shoes in shoe bags, and stuff them, and bury them inside my luggage rather than putting them into the outer pocket where they can get squished and wind up cracking. I put my shoes away in the closet (pocketed shoe organizer) rather than tossing them in the pile with my family's shoes. I do not leave gear shoes in a hot car to protect the rubber from wearing out. I stuff my tall boots so they don't sag over in the closet.
Gear: can last but often the elastic gives out, even when not worn at all. It simply degrades over time. Sneakers can degrade as well. If you are a runner, it's good to replace sneakers frequently, whether they look like they need it or not.
