I am 53, 115 LBS.  The size 27 fits me well.  These fit like a denim legging so I would call them denim Jeggings.  They are made of a very stretchy and soft denim & are skin-tight but still comfortable because of all the stretch.  They have true pockets, front & back.  They are very long  inseam is 31.

I really like the high waist. They are more comfortable than a low-waist version & hold everything in, in a very flattering way.

They are a very black BLACK.  I wash them inside out with other black items & hang dry.
