You're absolutely correct. Men haven't learned to finesse the questions "Do I look fat?" When the women ask that question, men have got to be prepared for a vague, noncommittal answer. As far as the various women's clothing size, as a woman, I find them confusing. The only and best way is to try the clothing on. There's old adage that says, "the cheaper quality garment the larger size" but the "better quality garment the smaller size". Even then sometimes it works and sometimes it doesn't.
The "do i look fat?" question has NO RIGHT ANSWER!!!!
My wife weighs 115 pounds dripping wet.
Yet she thinks she is fat.
I know what fat is. I weigh almost twice as much as her and I AM FAT!!!
But it's like Mike Myers said, "Once you've had fat, you never go back!" (Fat Bastard)
