Use hot wax (I use the cotton cloth strips - Body Shop used to sell them, you can wash/re-use)
Sugaring is brilliant is you can get hold of it, rinses off.
Or you can get Veet Hot wax.
Prep:
hair needs to be long enough.
bodyscrub/exfolliant with a non oily (I use BodyShop Pink Grapefruit -smells lovely)
Look at the direction of growth you'll find it grows up and down, you need to go against the growth to pull but with the direction to apply.
Talc - thin dusting.
I apply twice - once to pull up, once to pull down.
Thin layer of wax, put your strip on, leave a bit clear to pull.
Rub briskly, put your arm behind your head to keep the skin taut.
Keep the strip parallel to skin (so don't pull away ).
In one delft movement , go for it 
It gets easier and quicker.
