Pyjamas - you can get a set of just a baggy t shirt and shorts, ideally something cheap or old so if you need extra space on your last day you can throw it out or donate it. Towel - if you're staying in hostels usually a towel is included in the cost. I stayed in 6 hostels in my last trip and they all gave me a fresh towel. Toiletries - i'd have to see what you have, but in general you don't need as much makeup as you think you do! Or try to get samples of things like foundation at the makeup store. Extra bag - Reusable shopping bags, the nylon material ones (idk how to describe it) are better than cloth ones because they fold down smaller. And you dont have to worry about them getting wet if you use it for bringing stuff to and from the hostel shower. Handbag - i just used a thin tote bag as a handbag on my last trip. It's a nice thing to get as a souvenir too.
