Shopping tips: search these sites with keywords like “balletcore”, “tulle dress”, “pastel tulle”, “sheer midi dress”, or “tiered sheer dress”; filter by colour (pastel/pink/lilac/blue), material (tulle/mesh/organza), and seller location (Malaysia) to find faster.

If you want, I can pull live listings (prices, sizes, and direct product links) from any of these sites — tell me which store(s) or your preferred size/price range and I’ll fetch current options.
