I experienced a new one today... When you can squeeze past people in a theater or classroom row of chairs without making them all file out into the aisle! (Someday, I'm going to be able to squeeze past them without them even having to stand up).
When you have to shorten all your bra and camisole straps because they're starting to get too baggy, leaving gaps that make you look indecent!
When you can fold over the opening of your robe and tie it shut so it overlaps and closes properly. (This robe used to not even meet in the middle but I wore it anyway, how gross!)
When its easy to put your shoes on without having to put your feet up on a chair and hold your breath while you lean over to tie the sneakers. Oh it is nice that it doesn't hurt to put on shoes anymore. (meaning I have no excuse for not going walking anymore either! )
your shoes fall off while walking
your undies bunch up when you put pants on
your collar bones stick out
you can shop your old (like 10+ years old) clothes and find things that newly fit
you WANT to take full body pictures
you swim and almost flash everyone!
.. you walk into a clothing store and when you reach the plus size section located at the very back you remember these aren't even your sizes anymore and have to walk back to find your now smaller size.
You can now carry your water bottle in your fleece jacket pocket and it falls down against your stomach because there is so much room in the jacket... so you barely know the bottle is there.
