Madewell white skinny jeans

i thiught this was size 28 but it's a 26!! These are 0 flaws cause they were hardly worn out, and when i did wore them I had no idea why these barely fit. the jeans were not harmed while being worn. the button zipper etc all like new 😊 The material is 90% cotton, 8% polyester, and 2% elastane so there is a tiny stretch
