“Just because I can get this garment ON does NOT MEAN THAT IT ACTUALLY FITS.”
Now, for a fuller explanation of what I mean, search for “Fit” in the right upperhand search engine on this blog. Read, learn, embrace.
Repeat after me, darlings:
“JUST BECAUSE I CAN GET THIS GARMENT ON DOES NOT MEAN THAT IT ACTUALLY FITS.”

Also:
JUST BECAUSE IT FITS DOESN’T MEAN IT’S FLATTERING!
And just because it’s marked way down and goes on the body doesn’t mean it fits, is flattering, or is a bargain.
