R&M RichardsWomen's Plus Size Lace Pant Set

Are the pants thin material? In the close up of the picture, I swear you can see panty lines.

Whenever i look for petite plus size why doesn't it give the size i'm looking for, only plus sizes? do i have to purchase it by phone?

where do I find this pantsuit in 18 w petite?

What are the waist and hip measurements on 18w, 20w and 22w? you only have measurements listed for the top for all but petites.
