What size rucksack should i take for 2 months travelling round South East Asia? - girls rucksacks

I am only 2 months, but I am not one of those who will not be used as 2 pairs of shorts all the time, I take a lot of clothes! So I do not want all that I can, but want no problems. I thought 65l + 15 .. What do you think? Above all, the ideas of the other girls who were on the road ..
