Thanks, everyone! And I should also say, lest this become some sort of fetishization of skinniness sans context, that I'm also feeling better despite a few unrelated minor health issues, and am generally happier and more in tune with my body, and not just how it looks in jeans!
BJ, I'm not sure - thanks to the aforementioned health issues and my vacation, I'm totally out of an exercise routine, so I'm starting up a new bootcamp class this week. Gonna see how that meshes with my current eating habits for a few weeks and then evaluate. The weight loss clinic suggested a goal weight for me based on the body composition tests they did which is still 15+ pounds lower than where I am now. I haven't been that size since high school, if then, so I don't have any idea whether it'd be sustainable or not.
And a brief footnote to get it back on a fashion topic - I thrifted two pairs of shorts and another pair of pants this weekend, because I'm pretty sure my current shorts will not make it through the summer wearable. Not that shorts are a real issue here right now, it's maybe 60 degrees and raining.
