Just out of curiosity, what size were you when you reached 'goal' that you were happy with?

I realize that everyone's body shape/frame is different, but am honestly having a bit of a tough time determining what my actual 'goal' should be. Having recently started up a new exercise regimen (brand new), the scale isn't quite as useful as it once was. It's bouncing around a lot these past two weeks, but the end result is pretty much 'the same'. (give or take a pound or two).

So anyway - I'm wanting to try the 'test pants' way of gauging my progress, but don't have any smaller clothes I could use right now. I'm kinda tempted to go and buy some smaller-sized pants for this fun new experiment.

Thing is - what size should that be? One size smaller, two sizes smaller? The whole 'vanity sizing' going on isn't helping, and neither is the lack of consistency in clothing manufacturer's "idea" of a particular size.

What was your 'happy size' when you got to goal?

Thanks
