WOW!!
You can most definately see the difference. The first thing I noticed was your shirt!! It fits to you on the first picture, and its hanging off you in the second picture. WOW!!!
Also, your face is definately much thinner. You have the same smile in both, but your face is definately much more elongated now!
I agree with everyone else, take a picture in something tighter that shows your figure more. Then put that picture under those. You will definately see a difference.
Honestly, if I were you I would ditch the clothes that are too big and bite the bullet and get some that are smaller and more fitting. I know it's tough when you still have some to go. I know what that is like, but you will be amazed at the difference. That is when I started to feel so good about myself, and everyone started commenting on how much I lost. It was such a confidence builder! Start small. First I replaced my jeans and a few tops. Then I just slowly started buying things. I have a whole new wardrobe now and I still have another 20-30 pounds to loose. Not sure yet where I will end up. Plus its such a boost buying all those smaller sizes. I definately don't wear my XL baggy sweatshirts anymore either. This year while at WDW I bought a mens small. It's more snug, but definately more flattering!
Keep up the great work, you look fabulous.
