POOR QUALITY OF A R900 DRESS

S24 POPLIN MAXI A-LINE X NAVY - I BOUGHT THIS DRESS ONLINE ON 25 NOVEMER , I WORE IT ONCE ON 7TH DECEMBER... I WASHED IT AFTERWARDS..GUESS WHAT..THE DARK COLOURS CAME OFF AND MIXED WITH THE WHITE COLOUR AND NOW ITS DAMAGED..

FLIPPIN .. THIS IS A R900 DRESS ... CHECK REVIEWS UNDER WOOLWORTHS PEOPLE ARE COMPLAINING ABOUT THE SAME THING... WHAT NOW ? HOW DO I KEEP A R900 DRESS THAT'S WORN ONCE AND NOW IS DAMAGED?
