Hi there,
I am 5' 10 and would really like to get to 165-70.
At 180 I am easily a size 12-14, so at 165-170 I would guess I will be an 8-10 which may bee too skinny. I am very busty so I carry a lot of weight there and in my hips.

I got married at 20 at 155 lbs and was about a size 10. As I have gotten older I have built more muscle and carry the weight better. At my highest weight of 220, I was only a size 16 (go figure). I am trying to to stress out about the number, but go based on how I feel and look. I have a hard time losing the lbs with exercising, but the inches definately come off!

Regards,
