I found a Havaianas store on the 1st floor of Delay No Mall in Causeway Bay. Havaiana heaven! They have the largest slection for sure: plain, slim, printed, high heel, mid heel, kids, babies, etc. Only a few with beading or crystal options though. Another shop on the Ground Floor had a much smaller selection but a few funky crystal, chiso and metal detailing piece options.
FYI, I found Lane Crawford in Times Square to have the best options for the crystals - no surprise there I guess!
Thanks beetle - ok, I know this is sad but where exactly is the Delay No Mall? - I dont get out much y'see!
