Porto San Francisco black pants size 1 have a front zipper and an elasticized waist, the usual Porto feature. These pants are of a heavier weight appropriate for winter wear. They are elegant and drape well on the leg. They are comfortable and very easy to dress up in. There is no fabric tag as I bought these as a sample. I have enjoyed them, but have outgrown them. They are in very good condition and have lots of life left in them. Pricing reflects the lack of fabric contents and care information.
