Lost 25lbs - dropped 2 dress sizes - no-one has noticed!

When do people start to notice and say things like, hey you have lost weight or have you lost weight or you look great or you look fit or well or something. How much weight do you actually have to lose before your workmates, friends and family actually notice? Or is it the case that it was only me that noticed I was fat in the first place? Worst time was last week my friend that I had not seen for two years came to visit. On her last visit I was approximately 185lbs and now I am 158lbs but she said not a word about my weight loss so I told her. Have you, she replied, you cant notice! She is approximately 96lbs by the way! I mean is a 31 inch waist and 38 inch hips still considered to be really big? My target is 150lbs but I am now wondering just how much more weight I need to lose now? In this country size 0 is the size children wear and a 26 inch waist is a size 8, which is really small, 28 waist is a size ten and 30 waist a 12 and so on. I dont want to look like an adolescent child with no figure. Also I think that as we get older, we need a bit of flesh to keep us looking younger as there is a fine line between looking scrawny and slim. So if you were a size 10 in your 20's then you need to be a 12 or more now to keep you looking young and plump out some of those wrinkles!!!!!
