Essentials to live in Sweden

Well winter gloves and winter hats socks are easy and cheap to find in sweden
I recommand to pack along winter jacket and sport clothes

Nothing. if you cannot get something here you can use Amazon I moved in from Poland and had no difficulties in buying what I needed. Food is more expensive but clothes, IKEA things are almost the same prices as in Poland... which is quite scary when you compare Polish average salary to Swedish...
The only thing is hard to find here are friends...so pack group of best friends with you!

I agree with Maryshaa, although the cost of postage can be quite high, for example I was looking at buying an item which would have been the size of 3 very small pencils for drawing, the seller tried to charge me £26 for shipping, the item was only £2.50   so be careful if you go that route.
Friends are also hard to make here, and honestly most guys I have talked with only looking for a quick one nighter which they are soon to learn I don't give out! 
Good luck with your move.

i really want to meet you at sweden i like t come there
