Thanks so much for all the thoughtful replies to this thread. I really appreciate them. My new job allows me a little personal internet time at work so I peeped at this thread at intervals in the day, though I was quite busy and couldn't reply at the time.
I'll respond to various thoughts mentioned rather than the people.
Firstly, Yes it is a bit like a change of season - I always find that a bit difficult. But in that case (for me at least after 5 years on YLF) it is more like "how to I do it again?" and soon I remember what I wore last year!! And I don't have that many FFBOs that seem right!.
Secondly climate is indeed a factor. In my old town for a fair bit of winter I worked on the basis that so long as my coat and boots were okay I was pretty much covered. I rarely took them off. Now I am dressing for slightly warmer surroundings with the coat mostly for my mornings and evenings.
Thirdly I have written elsewhere about not seeing bootcuts much at all. And I have one pair of jeggings that is literally ripping apart, one pair that is really too small ( though I have squeezed into them for 2 casual fridays) and a pair of straight legs that are too tight around the waist except when I am at the lower end of my weight range. But right now I am a pound or 2 over the top or my weight range. And two good pairs of bootcuts that have gone to the suitcase under the bed!
And I can relate to the points about not being known here. At church I don't know who is new and what happens. And we are attending a mostly studentish congregation (while DH is making preparations for another student church) - the exact demographic lacking in my previous country church!
Wearing smarter clothes to the office makes me want to go more casual by contrast on Sundays too, in addition to other people dressing more casually.
I have ordered a sweater and some jeggings, though the latter are wait listed so could be ages (I found normal skinnies uncomfortable). I went looking for a belt today so I could tuck at the office, but came back empty handed. I don't look good in skinny belts but there were few wide ones around.
And I have been thinking through a new dress purchase. I know I want it do be patterned and the style not to be fit and flare, but I don't know if I should go stretch or woven, loose or fitted. I am thinking about how it could be worn on weekends too.
There was food for though on the "reinvention" issue too. Will continue to ponder. And make sure I sleep enough!!
Thanks again!
