Way to go! you are doing great
My take on it. Is i buy clothes from same places as when I was whicked fat.
I was telling a co-worker of mine through my long journey of being overweight and dieting that it is different at different clothing stores.
She telling me goto walmart or kohls to get cheap clothes. And I had to explain to her what i discovered.
For instance a long time I go I found a size 16/18/20 at say a jcpenneys or sears was not the same as a size 16/18/20 at a lane bryant, august max, or catherines.
That when "Plus" is used for bigger sizes instead of "womens". They tend to get a little larger than what a "womens" size would be.
Another thing I noticed was the Plus Size stuff "stretches" So you can actual get buy sometimes having a smaller size than what you really are.
I recently 2 months ago bought 4 polos from catherines. Same brand, same shirt different colors. 2 of the shirts are smaller in length then 2 other shirts.
But for me the above is still doing obessing and trying to justify why you don't fit in it.
Have confidence in your weight loss. Do you see it in the mirror?
The bigger question to me is; At what weight will you believe and have confidence in you having this under control?
I complete know what you mean, For me I had two points. One was when I hit below 300. The other point was just recently. When I gave away all my whicked fat clothes a few weeks ago. When I hit the double digits in loosing.
Last 2.5 weeks I been sorta freaking out because this month my period was whicked weird. I didn't loose the normal amounts(still lost but less), I felt really fat. My boobs felt bigger. Worrying that oh crap, this better not be it. But you know what it was fine. I am back on track I think to whatever hormonal thing was going on. And tommorrow, weight day, I fairly certain I will be back on track.
For me, if having those clothes is causing you to obsess and doubt, then return them.
Get something that is snug and fits for the most part.
But don't let it derail you.
Trust, trust, trust the scale and body measurements you are taking. And don't go by what size you are in "new" clothes.
Oh and if you are worried about loosing muscle mass, then do some weightlifting to keep it. That is what I am doing. It seems to be working. As I am becoming more "ripped" like I was when I was younger.
You are doing so great! Don't forget that...
