Short answer: Taylor wore Louis Vuitton's cognac/brown Isola sandals for her engagement announcement — you can buy that exact pair at LV boutiques in Kuala Lumpur, or find very similar (and much more affordable) block-heel/slingback sandals at Malaysian retailers such as Charles & Keith, Zara, Zalora, Vincci/Padini, or on local luxury resale sites.

Where to shop in Malaysia (options from exact to budget-friendly)

• Exact designer pair — Louis Vuitton boutiques (KL): Pavilion KL, Suria KLCC, The Gardens Mall, The Exchange TRX (book an appointment or check stock in-store). (us.louisvuitton.com)
• Mid-range (very similar look: cognac/tan block-heel slingbacks and sandals) — Charles & Keith (wide Malaysia presence + online; e.g., dark‑brown double‑strap block‑heel slingback). (charleskeith.com)
• High‑street / fast fashion — Zara Malaysia and other mall brands carry leather/PU block‑heel sandals in brown/cognac tones. Good for a close look-for-less. (zara.com)
• Large local online marketplace — ZALORA Malaysia: lots of brands and filters for “brown / block heel / slingback” so you can compare styles and prices. (zalora.com.my)
• Local/affordable brands and department stores — Vincci (Padini group) and multi-brand department stores found at major malls (SOGO, Parkson) often stock brown block‑heel sandals. (sogo.com.my)
• Pre‑owned / resale (if you want a past-season LV pair at lower cost) — Reebonz (Malaysia) and international resale marketplaces (Vestiaire Collective) are good places to check. (Check shipping/returns and authenticity policies.) (milled.com)

Where to go in person (KL hubs)

• Pavilion Kuala Lumpur — luxury boutiques including Louis Vuitton and many shoe brands. (pavilion-kl.com)
• Suria KLCC — another major mall with flagship stores and department store sections for shoes. (en.wikipedia.org)

Quick buying tips

• Search keywords that work well: “cognac/tan leather block heel sandals,” “brown slingback block heel,” “Isola sandal” (if you want the LV name).
• Look for a 4–6 cm block heel and a single wide front strap or two-strap slingback to match Taylor’s look.
• Try in store if possible (fit and strap comfort vary); check return policies for online buys.
• If you want the authentic LV Isola, call the LV boutique to check stock or ask them to notify you.

If you want, I can:

• Look up current stock/links for a specific size in a particular store (e.g., LV Pavilion KL, Charles & Keith, Zalora), or
• Pull 4–6 visually similar options across price ranges and show prices available to ship to Malaysia.
