Low cost?

LOW COST?If you don't know what low cost is well let me tell you, it's brands like Zara, Mango and so on. But I don't think this is low cost right? Is low cost turning high costSi no sabéis lo que es low cost bueno pues os lo digo, son marcas como Zara, Mango... Pero no creo que esto sea los cost, ¿verdad? ¿Low cost se vuelve high cost?
