Do you say "trousers" or "pants"?

Both are correct. The word "trousers" is widely used in the United Kingdom and other European countries. The word "pants" is commonly used in the United States and in Canada. In these countries, trousers refer, often more formally, specifically to tailored garments with a waistband and (typically) belt-loops and a fly-front. In Australia, trousers and pants are synonymous.

I live in india.we say pants for the full and trousers for shorts or bermudas.

Here, in Malaysia, the long ones we call them trousers or long pants, whereas the short ones we called them pants or short pants. Hehe... the short, tight and sexy ones are called hot pants.

Being English, as far as I am concerned, trousers are what you wear on the outside and pants ar what you wear underneath. Formally our underwear (for men) are known as 'underpants' and omen use the term 'pants' or 'knickers' for those, as opposed to the Americanism 'panties'. I don't know why but that word makes me cringe. Something to do with the stiff upper lip, I suppose?

People here in England call them trousers, so that is the correct English!

Yes, in the UK we call them trousers. We don't use the word slacks very much. Americans prefer the word pants. I suppose the correct word for you to use depends on whether you're going to be talking to British people or American people. As Laura20 says, when British people talk about pants we're talking about our underwear, and the word generally refers to male underwear (boxers, briefs etc..) The word we use for female underwear is knickers.
