I'm so confused about which baby carrier to buy! Does anyone know a store that would let you try on a few before buying one?

You can go to www.babyslingsandcarriers.com. Their showroom is located at Jalan Pemimpin and they have many carrier brands there that you can try on for a fee of $20. If you buy a carrier from them, this fee is waived. They have popular brands like Ergo and Tula.
