I agree with
swimgirl. My sister wears a size 20 and a size 10 pair of underwear. She weighs about 190 lbs. She is 5'4".
I am 5'6.5" and I currently wear a size 26 and a size 10 pair of underwear. You can see below what I weigh. It is almost 70 lbs more than my sister. The reason why I mention the underwear is because I was telling my sister the other day that I felt a little embarassed getting size 10s when I am out buying new ones. She said to me " Boy, you must have a small butt, then!" I have been active in the past so my muscles are probably more toned than my sister. Smaller? I don't know. I didn't ask her what brand of underwear she buys. Different manufacturers cut their clothing differently. That is why most of my clothes are in size 26 but I have even a few 22-24s that I can wear--like the Elizabeth label by Liz Claiborne. Did I also mention I wear a size 46DD bra? My sister wears a size 42C.
The point that I am making is that all of us carry our weight in different areas of our body. I have a classic hourglass figure. My waist is exactly ten inches less than my hips.
Sometimes, it takes me 30 lbs to drop one size also. It bothers me too when I hear of people dropping sizes quickly but if that is the way my body is, then that is the way my body is. I would work more on self-acceptance and just be glad you are going down and not up.
In your photo you look like you might have an hourglass figure as well. I would keep working out and keep up your good work. When you get done, you will have the kind of figure guys love. Womanly not waif like.
Good luck!
