Elegant Purchase Website Design

I’m looking for a clean, classic-and-elegant layout for a purchasing website. At this stage I only need the design itself—no coding or implementation—so high-fidelity mock-ups in Figma, Adobe XD, or Sketch will be perfect.

Here’s what I’d like to see:
• A polished homepage that immediately conveys trust and sophistication.
• A flexible product listing template and a matching product-detail page.
• Simple cart and checkout screens that keep the same refined look.

Feel free to suggest tasteful typography, a muted color palette, and any subtle graphic accents that reinforce the classic style. I’ll supply my logo and sample product shots once we start; you can use placeholders until then.

A quick turnaround and clearly organized source files are all I require for delivery.
