Well, I'm 5'3'' and my goal is 130 - 135. I could be incredibly happy at 125 or 128... or even as low as 120. That would be nice, but in my eyes, not very realistic FOR ME.
I'm 165 now, and looking quite the chubbo. No m'am, not impressed! Plus, it's HARD to find clothes that fit that actually look good, and don't make me look "too frumpy" or "too cowish" or "too sackish".
When I was 138 last summer/fall, I was able to wear some really nice clothes, and I really felt that I looked good. And more importantly I FELT FABULOUS.
Fat feels bad.
