Short answer: It was a Polo Ralph Lauren black‑and‑cream striped silk‑blend halter dress — you can try Ralph Lauren stores or the RalphLauren Malaysia website, and if that exact style is sold out you’ll find very similar striped halter dresses at Malaysian fast‑fashion and rental boutiques. (Fashionista.com)

Where to look in Malaysia (options that work fast):

• Ralph Lauren (first place to check for the exact style or restock): official Malaysia site and Ralph Lauren boutiques in KL (Pavilion, Suria KLCC, Mid Valley). (ralphlauren.com.my)
• Department stores/stockists that carry Ralph Lauren in Malaysia (may help if main site is sold out): SOGO, Isetan (Suria KLCC), Pavilion. (SOGO.com.my)
• Local online retailers with large dress selections (good for near‑matches): Zalora, FashionValet, Pomelo, Zara Malaysia — search for “striped halter dress” or “striped silk dress.” (zara.com)
• Designer/designer‑rental and evening gown boutiques (if you want a higher‑end or one‑time wear match): Dressaville (Kuala Lumpur), Clarissima, Vogue Lease — they rent/sell gowns and can often source or alter similar looks. (dressaville.com)
• International multi‑brand sites that ship to Malaysia for more options (if you want exact designer pieces or similar silhouettes): Net‑A‑Porter / The Outnet / Farfetch (check shipping & duties). (theoutnet.com)

Tips to get the same look quickly

• Call your nearest Ralph Lauren boutique (Pavilion or Suria KLCC) to ask about restocks or similar striped halter/smocked bodice styles before traveling. (Pavilion-kl.com)
• Search local stores for keywords: “striped halter dress,” “silk‑blend halter,” “smocked bodice striped dress.” Retail filters (length, fabric, halter neck) help narrow matches. (zara.com)
• If sold out, consider renting a similar striped halter or a black‑and‑white silk dress from Dressaville, Vogue Lease or Clarissima for photos/events. (dressaville.com)
