Okay, I just hit your "About" page:

You're 5'10", so most assumptions don't apply on women typically 5'3"-5'6".
From the two pics with the tape measure, it looks like your bust (around nipple) is 46" and your hips are 42".
Wow! You are even more extremely curved than I thought!
I couldn't get a "good feel" for your hourglass from head-to-toe from the free pics, but I'll look a bit deeper.
If you are, indeed, a 46H-26-42 (which might be defined around a 40F-26-42 under some US measurements, depending), then you are well beyond a standard hourglass size, with +14-16" beyond waist, which is typically only +9-12" for most hourglass shapes.
That's absolute model perfection in my (among most other, male) books!
