Great — here are the best places to shop for Y2K “dress‑over‑pants” looks in Malaysia, separated by online, second‑hand/vintage, and physical shopping areas, plus search tips so you’ll find the exact silhouette you want.

Online marketplaces (fast, lots of options)

• Shopee Malaysia — massive selection of new and preloved Y2K / slip dresses and low‑rise pants; use keywords like “Y2K dress”, “slip dress”, “babydoll dress”. (brandradar.org)
• Lazada & Zalora — good for new-brand pieces and curated Y2K drops; Zalora is a major Malaysian fashion retailer. (brandradar.org)
• Temu / Ubuy — for inexpensive imports or harder‑to‑find international Y2K items shipped to Malaysia. (brandradar.org)

Resale / preloved platforms (best for authentic Y2K pieces)

• Carousell Malaysia — big market for genuine Y2K and preloved dresses, slip gowns and vintage pants. Search seller hashtags and filter by location. (brandradar.org)
• Depop / international vintage sites — useful if you don’t mind international shipping (look for sellers that ship to Malaysia). (brandradar.org)
• Local curated preloved shops (example: Refash and similar chains) — cleaner, curated preloved options if you prefer inspected items. (brandradar.org)

Physical shopping areas & malls in Kuala Lumpur (best for in‑person hunting and mixing pieces)

• Bukit Bintang area (Sungei Wang Plaza, Fahrenheit88, Berjaya Times Square) — youth fashion hub with many thrift/vintage stalls and small boutiques where you can hunt Y2K layering pieces. (en.wikipedia.org)
• Kenanga Wholesale City / KWC Fashion Mall (Pudu) — huge fashion wholesale/retail mall with many small vendors (good for affordable trendy pieces to layer). (en.wikipedia.org)
• The Exchange TRX & other large KL malls — carry contemporary brands that sometimes run Y2K revivals. (en.wikipedia.org)

Thrift & vintage stores / markets (one‑of‑a‑kind finds)

• Independent vintage stores and market stalls in KL (Sungei Wang and surrounding streets) and curated vintage boutiques — best for true early‑2000s pieces like slip dresses, babydoll minis and low‑rise pants. Use local Instagram seller tags (#y2kmalaysia, #y2kvintage) to spot restocks and pop‑ups. (brandradar.org)

Search & buying tips (to find the “dress over pants” silhouette)

• Use multiple keywords: “Y2K dress”, “slip dress”, “babydoll dress”, “dress over jeans”, “dress over pants”, “ruched dress”, plus “preloved / vintage / Y2K”. (brandradar.org)
• For marketplaces, filter by “preloved” or sort by newest/closest seller; ask sellers for flat measurements and photos of the item worn (important for layered looks). (brandradar.org)
• Pair shorter slip or babydoll dresses with low‑rise straight/bootcut jeans, cargo pants or flared trousers for an authentic Y2K silhouette — try searching within listings for outfit photos to confirm the “dress over pants” styling. (pinterest.com)
