Yep. I enjoy goth clothing, and I often wear corsets and the likes, and you just can't overeat when wearing those, or you feel like you're going to explode.
(Besides, as silly as it may seem... when I'm wearing such elegant clothes, I feel like eating in an 'elegant' way, too: not eating quickly, not eating with my fingers (chicken wings, argh!), etc. I mean, if you're clad as a lady, you don't want to be caught pigging out, right?
