What a great holiday careof123. You will want your feet to look their best in sandals, so try a pedicure well before you are due to leave and have another just before you go. Usually the therapist will trim the toenails, push back cuticles and remove hard skin, very much like a podiatrist would. A good beauty therapist will also massage your feet which is the part I like best. I always choose a dark polish for my toenails which tones rather than contrasts with whatever I have on my finger nails. It's a long time since I lived in a hot climate and since I was young and tanned at the time, didn't need much make-up apart from navy blue eye liner - well, it was the 1960s! - and quite a pale lippy. I wouldn't have my lashes tinted since I have very sensitive eyes nowadays, but that's a personal choice and you might take advice from a good beautician and also find out what kind of foundation would be best in a hot climate - remember to get one with a sunscreen in it.
