"I Never Thought I’d See So Much Purity Of Pattern"

A pervy come-on of a sales-pitch from a ladies' clothing salesman:

I never thought I’d see so much purity of pattern. Absolute rightness. I must please you, and I think I can. Don’t fail me now, because I may never trust myself with a woman again, ever. Try it on. I’m sure, absolutely, I can please you. Show me. Wait for me.
