Whenever I get lower than 150, I start becoming quite small - I am pear shaped and definitely a size 6 on top... but my butt is still a size 8/10 (depending on brand). From 150 to 135 - makes a HUGE difference in size. Thats when people start saying "Wow, stop losing! Or you'll waste away to nothing".
What also makes a huge difference is how fit you are - no muscle, then larger at a smaller weight.
One cannot think well, love well, sleep well, if one has not dined well. - Virginia Woolf
