I'm usually quite tolerant of spelling mistakes, considering I teach English. That's probably because I spell things wrong all the time too and have edited many many many posts after rechecking my spelling.
But having seen so many recent cases on this discussion forum, it's starting to drive me a bit bonkers. Let me provide some definitions:
lose (NOT HAVE) verb past tenses: lost, lost
1) to no longer possess something because you do not know where it is, or because it has been taken away from you:

2) to stop feeling something:

3) to have less of something than you had before:

4) If you lose time, you waste it:

lose (BE DEFEATED) verb lost, lost

2) describes hair that is not tied back:

3) describes items which are not fixed or held together or to anything else:

So if you LOSE weight, your clothes will probably be LOOSE. Got it?
Okay, rant over, never to mentioned again, unless you really prod me on the point.
