It's a fashion rule [1] we've heard time and time again: if you haven't worn something in six months to a year, it's time to toss it. But Queen Letizia of Spain makes her own rules, thankyouverymuch, and for Red Cross World Day in Albacete, the royal broke out her favorite windowpane top, which she's repeatedly worn, on occassion, for years.

Letizia's choice just proves that although you might not wear something frequently, classics — and especially printed pieces [2] — are worth holding onto, since they'll always be in style. Read on to see Letizia's Hugo Boss top, then shop a similar piece for your own wardrobe.
