Short answer — apps/marketplaces where you can reasonably find “Penny Lane”–style coats in Malaysia:

• Zalora (Malaysia) — large fashion app carrying local and international brands and vintage/retro-style outerwear. (apps.apple.com)
• Shopee (Malaysia) — major local marketplace where individual sellers list vintage/replica/“Penny Lane” / Afghan-style coats. (search on the Shopee app for “Penny Lane coat”, “afghan coat”, “shearling coat”.) (Pinterest.com)
• Lazada (Malaysia) — another big multi‑seller marketplace with coats in a wide price range (look for “Penny Lane”, “afghan coat”, “70s shearling”).
• Carousell (Malaysia) — classifieds-style app good for secondhand / vintage Penny Lane coats.
• eBay Malaysia — listings for vintage and new “Penny Lane” / Afghan / shearling coats shipped within or to Malaysia. (eBay.com.my)
• Etsy / Depop — international vintage/handmade marketplaces where many sellers list Penny Lane–style coats and ship internationally to Malaysia. (Etsy.com)

Tips for searching in the apps

• Use multiple keywords: “Penny Lane coat”, “Afghan coat”, “70s shearling coat”, “vintage suede shearling”, “boho fur trim coat”.
• Filter for location/shipping to Malaysia (or seller country) and for “preloved/vintage” if you want authentic older pieces.
• Check measurements, material (real suede/shearling vs faux), and return/shipping policy before buying.

If you want, I can:

• Search any one of these apps right now and show current listings (I’ll need to look up live stock).
