Size XL is not XL

I wear size 46 with a height of 170cm.
I ordered the size XL.
The leg was too short, so I hung the tights between step and knees.
When I cut off the feet, I was able to pull the tights higher, however,
even to just below the rear sight. UnterŽm dress this looks very squashed, because the
Lifebelts are above the tights ;-)
I would have liked that the tights extends to Tailie and the legs are longer!
