New with tag 'Marks & Spencer' black linen blend 'Bootleg' trousers 

Above I have listed under 'Leg Style' as 'Bootcut' because there is no choice for 'Bootleg'

Size 18 Long
Waist 38"
Rise 11.5"
The measurement across the top of the thigh is 13"
Inside leg 32"
Across the hem is 11" this is wide so please check it is the width you want

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 measurement please lie trousers flat & measure from the crotch to the hem
