Very low-cost, trend-focused options

Local designer / niche platforms

• Local boutiques on platforms like Zalora and independent brand sites (Love, Bonito, local concept stores) — good for more unique pieces and better fit for local tastes. (apps.apple.com)

Shopping tips for Singapore online stores

• Check shipping, delivery windows and taxes: many Singapore sites offer same‑day/next‑day or standard 2–5 day delivery; marketplaces may vary. (apps.apple.com)
• Returns & sizing: look for “free returns” or 30-day return policies (Zalora and several local brands advertise such policies). If you’re between sizes, check brand size charts — Asian cuts can run smaller. (apps.apple.com)
• Payment & discounts: use app vouchers, e‑wallets (GrabPay, ShopeePay), and sale events (10.10, 11.11, 12.12) to save. (apps.apple.com)
• Sustainability/quality: if you care about materials or labour practices, prefer established brands or check product descriptions and third‑party reviews before buying (fast-fashion sites vary widely). (reuters.com)

If you want, I can:

• Suggest 5 specific stores/apps based on your style and budget (e.g., minimalist, streetwear, workwear), or
• Compare return policies/average delivery times for 2–3 stores you’re considering.
