Bringing one of this fleece lined jackets with water proof outer I bought from a shop on Cameron highlands. This one has a hood which is good.
Then of course will add skincare to this luggage and then done.
For shoes I am bringing sports shoes that look fashionable I am wearing Skechers shoes meant for running.
When going to Malaysia and travelling over the causeway I shall be wearing one t shirt, one reebok hoodie, one reebok joggers and bringing the fleeced lined jacket in my hand carry to wear if cold in the coach.
The hand carry I shall be bringing is some thing like this.
I will be carrying passport and money in my hand carry. Passport and travel documents can be put in a passport type folder or holder file for travel. Can be purchased from daiso. The money can be put in various purses purchased from souvenir shops overseas like Vietnam or Thailand. It looks stylish and easy to access the money when travelling.
Have a great day!
