It's will be great time for good memory with Ao Dai in Hoi An. You no need to buy but can rent 24 Hrs. with cheap price (Wow). Their shop wasn't so far from old town. You can rent bicycle to there and no need to return at their shop, they will pick up at your hotel that you stay.
Anymore, got support from staff, Mr.Vinh. He was nice and good relationship also. Thank you so much.
