Adrianna19 packing party:Singapore

Please help me what to bring on my 5 day vacation in Singapore. My friends and I will be there to explore the country. We will go to safari, sentosa and other exciting places. Of course we will go shopping and a lot of night out and clubbing probably Hardrock. I will also attend a highschool reunion with my classmates working in Singapore. I also need one formal wear for my job interview there. So I need few clothes for this trip.

Thanks in advance!
