You can buy Olive Oil in Pharmacy with a "Cross". the brand that I used is MONA 100% Olive oil.
Dress you can found in "Woman Street" 3rd column from Mong Kok Road. The sale is lady. About $100 each if you bargain with Her. The opposite side and another stall is managed by a "阿叔" which has more different types of dresses. Or in MaOnShan 新港城的shan shan, around $130 each dress. But I brought two discounted dress with only $150 there.
Don't buy trousers with elastic cloth in Mongkok centre (normally is slim type). I brought three in the shops on G/F and 1/F. After washing, 縮水。
I've experience that most of the shops without brand have similar or same types of products. I think they are come from the same dealer. So price must be compared.
it's right. Many shops with Brand is on sale now. I brought a pair of trousers with only $100 in 妮妮 (good quality), very very cheap but only 3-4 types would be so cheap. if you have time, spend more in brand shops is recommended.
