Visited this museum yesterday - was a delightful way to spend an hr or so away from the hustle and bustle of the city.
Something that surprised me was the size of the estate - the building that displays all the ao dai is an airy barn with both Vietnamese & english descriptions, and is amongst a beautiful garden/park setting. Visitors are able to hire ao dai and take photos amongst the gardens - very picturesque with a lake, small boats, small bridges... lots of young people around taking beautiful photos. A little run down but still plenty of rustic charm.
Getting there way easy enough - we took a grab car which was around $300,000 VND from Sofitel Hotel and was driven up to the gate of the museum. On the way back we felt a little more adventurous and took the bus back - was a little tricky as no proper bus stop but with some directions from the staff from the museum we were able to stand in the right place (at the t-intersection on the main road/turn off for the museum) and flag down a bus (no. 88). Much cheaper at $6,000 VND a ticket back to HCMC and great experience seeing local life on a bus.
