Love love love Madewell. The clothes are quite literally made well. I know when I purchase from them, I am purchasing a garment that will last me for years without ripping, tearing, unraveling, etc. Their v-neck T-shirts are the best, and when they are on sale, very affordable, too. I recently received a 100% silk polka-dot dress from this store that is the nicest dress I have ever owned. Completely luxurious and stylish.
I also purchased several pairs of shorts from them over the summer that quickly became my favorite pairs. I also own a chambray Oxford shirt.
Next, I want a pair of madewell jeans or a cardigan. Their shoes are also to-die-for.
Ever heard the saying that "poor people can't afford to buy cheap things"? It argues that if you bite the bullet and pay the price for higher quality clothes, you won't need to replace your clothes as often, therefore saving you money. It's how I justify paying the relatively high prices here :)
