LOL. I'm 5'0" and haven't been 100 lbs since the eighth grade. I was buying jeans in the boys section of farm and home.
BMI is ridiculously inaccurate. There are so many factors that it does not take into consideration. For example, at 5'0", I'm short, not petite. My shoulders and hips are just as wide as a taller woman's. I just have a 25" inseam. For me 120-125 is ideal, and that requires rigorous maintenance.
I have a friend who is just an inch shorter than me, but she is truly petite. Even when I get to my goal (25% body fat), we won't be borrowing clothes from one another. EVER.
I recommend looking at your Body Fat percentage. 30 % is obese. Under 18% is too thin for women. I think 20-25 is considered healthy and fit. You can now get body composition scales that are accurate within .5%. I took my Ironman brand body composition scale with me and had the caliper body fat analysis done. The two test were within .5 % and both tests are supposed to be accurate within .5%
There are several hand held devices that do that too, but I like having it in my scale.
There is also the waist to hip ratio. The ideal waist-to-hip ratios are 0.80 or lower for women and 0.95 or lower for men.
