Apart from having packed your suitcase properly so that everything stays in place it's just as important to think through what to put in your purse.
Just imagine the scenario what would happen if your luggage gets lost. You'll be standing there in a foreign country without any clothes etc.
So in case something like that might happen to you it's better to be prepared.
First of all, I'd choose a big purse with a zipper for traveling. That way no one can get into your purse without you noticing it that easy. Also you can take underwear, a few clothes, a thoothbrush with you just in case your suitcase is missing.
I guess I don't really have to remind you to put your passport, I'D card, some money and a hand sanitiser in your purse as well. ;)
I guess if you'll keep in mind all the things I've told you in each part of the Travel Series posts you'll be traveling on the safe side. :)
I Wish you a merry Christmas and a happy New Year!
