I bought jeans from F21 online site. I washed the jeans just once, and the jeans gone hard like rocks! I wasn't even able to wear it at all because it's the jeans scratches my legs when I put them on and it's not wearable. And yes, it shrinks after I washed it. I didn't use hot water, just room temperature water cuz I was concerned it would shrinks. And, unfortunately, it shrinks even with room temperature water. I will never buy jeans from F21 anymore.
