You are not alone! If I find a style/brand/item that really works, I buy multiples. Clothes shopping, especially online, can be such a gamble. I was just admiring a sweater this morning, when it popped up under an entirely different name. A little digging suggested the sites were scams or at least very poor quality. (Oak & Harper, Bennet & Clarke, Kaila Boutique . . .)
I bought the first pair of these Eccos in yellow, and as they went on sale, bought two more pairs. I ended up with four of the Palmer cut pants from Loft, in twill and corduroy, because they fit me perfectly.
I also own FIVE of the Maeve Carys sweaters, though I don't have Finds for all of them. They're just so good - a flattering fit, lovely soft fabric, interesting colors and patterns. No sign of pilling after five years of steady wear.
