New with tags 'Marks & Spencer' aubergine active waist 'Regular' trousers

I HAVE STRUGGLED TO PHOTOGRAPH THE EXACT SHADE/COLOUR & DIFFERENT MONITORS SHOW SHADE/COLOUR DIFFERENTLY
ON THE WASH LABEL IT STATES THE COLOUR IS 'AUBERGINE'
THE CLOSEST COLOUR I CAN GET TO UNDER THE CHOICE ABOVE IS PURPLE
IF SHADE/COLOUR IS A PROBLEM PLEASE DON'T BUY, THANK YOU

ON THE LABEL IT STATES WAIST 40", THIS IS INCORRECT
THE WAIST MEASURES 38" 
TO CHECK YOUR WAIST MEASUREMENT PLEASE FOLLOW THE INSTRUCTIONS BELOW
IF YOU BUY PLEASE LET ME KNOW THAT YOU ARE AWARE OF THE LABEL FAULT, THANK YOU

WAIST 38"
Rise 12"
Inside leg 33"
Across the hem 8.5"

To check the waist size on trousers you already have please lie them flat, don't bring the front of the waist up to match the back of the waist
Lie them flat & measure across the very top inside the waistband that is & double the measurement to get your waist measurement
Please keep in mind different styles of trousers sit differently & the rise makes a difference too

To check your inside leg length please lie trousers flat & measure from the crotch to the hem
