Weight loss does mess with your head, and it can take a very long time for your brain to catch up. Please realize that, for awhile, you will be seeing a very different person in the mirror than everyone else is seeing.
I found it very helpful to apply two tactics, to speed this process along:
1) Shopping A LOT. Even if I didn't buy anything, the process of trying on clothes in various sizes and looking at myself in the mirror in the clothes with smaller size labels helped jolt my brain along.
2) Find a few trusted friends who will not lie to you. (Your hubby may or may not be one of these people). Have them point out women who are the same size and shape as you. At first, you will not believe them at all, because your brain has yet to catch up and you're still thinking and seeing yourself at your larger size. Eventually, it'll start clicking in that yes you are thinner -- like that woman right there -- and she is wearing a top that does not cover her butt completely and looks quite smashing in it. Not only that... but she's belting!
Re: the belting. I am only now accepting that yes, I really can belt, and yes, I really can tuck shirts in. Even into skinny jeans!! I hope soon to post some WiW proof. When I first adopted skinny jeans I would only ever wear them with a tunic or voluminous top, something long enough to hide hips/rear. I am beginning to realize I do not have to. I can tuck. Wow. But it's taken THIS LONG.
