Its depends on the style of the trousers, LUC does many different cuts.
With these kind of brands that have thier own unique sizing, I always try to try it on first.
The pants your referring to seem to have a wider leg, they don't look that tapered to me in the photographs.
However, the auction refers to them as tapered and I own a pair of LUC pants with that cut, so I'll tell you how it is.
quite relaxed and wide with a relatively long crotch, and the pant legs are quite wide to begin with, but become small very close to the bottom of the legs.
Combined with the length, I found it to give an overall effect of baggy-ness.
