Short answer — look on Malaysia’s big general marketplaces plus the vintage/second‑hand apps. Good places to find Penny‑Lane–style coats (suede/afghan / faux‑shearling / 60s–70s boho coats) are:

• eBay Malaysia (eBay.com.my) — lots of vintage / “Penny Lane” listings. (ebay.com.my)
• Etsy (mobile app) — many new & vintage “Penny Lane” / afghan / shearling coats that ship internationally. (etsy.com)
• Depop (app) — active Y2K / vintage Penny‑Lane style listings from independent sellers. (depop.com)
• Poshmark (app/website) — resale listings for Penny‑Lane / shearling coats. (poshmark.com)
• Carousell Malaysia (app) — local preloved / vintage coats (good for in‑country buys / meetups). (carousell.com.my)
• Lazada (app) — large marketplace where sellers list faux‑shearling, suede and boho coats; useful for new, lower‑price copies. (lazada.com.my)
• Zalora (app) — fashion app/marketplace in Malaysia that stocks coats and branded outerwear (use for current-season takes on the style). (zalora.com.my)
• Specialist / wholesale sites and independent sellers (Gem.app, AfghanCoat, etc.) also list Penny‑Lane–named coats if you want reproduction pieces. (gem.app)

Quick tips for searching:

• Use keywords: “Penny Lane coat”, “penny‑lane”, “afghan coat”, “faux shearling”, “suede fur trim”, “70s/60s vintage coat”, “Y2K Penny Lane”.
• Filter for seller location or “ships to Malaysia” if you need local shipping.
• For authentic vintage pieces prefer resale apps (eBay, Depop, Poshmark, Carousell); for new/reproduction pieces try Lazada, Zalora or specialty sellers.
• Check photos and measurements carefully (vintage sizing varies) and confirm returns/shipping before buying.
