Praise be - the thread is still alive!
I like the "slow January" idea; the original Frugal thread really changed my mindset, even though a consistently crappy year persistently prevented me from keeping up with it... 
I really hope that bootcuts don't supplant skinny/straight leg jeans for a while! I lived in bootcuts in the noughties and loved how comfortable they were, but I've finally come around to the slimmer silhouette because it looks so much better (on me, at least) with floaty layers and big, heavy boots. I've finally found something that works for me, so I really hope the high street doesn't force me to change again!
I think the best thing I've done for my appearance/confidence/wallet in 2013 was recognising the unpopular 1990s teenager "look" that makes me feel happy, and starting to find comfortable ways of toning it down for the majority of days when it's not appropriate to dress up.
The original thread made me think a lot more carefully about colours and shapes, and it helped me to figure out A) what I feel good in, and B) how to get the greatest amount of use out of my clothes.
I now pretty much live in black or dark grey, with accents of colour in deep jewel tones, or navy, or dusky purple, because I like them and I'm pretty sure they look best on me. I've spent most of the year wearing skinny or straight jeans and layering vests, draped cowl necked jersey tops, floaty waterfall cardigans or understated blazers, and Dr Martens. A-line leather mini skirts, 90s tube skirts, and cranberry/petrol cord jeans are pretty much as "dressed up" as I get now. It's great - I always feel appropriately dressed and get lots of compliments, even though I'm not spending anywhere near as much time or money on my appearance!
Oddly, I've found that the above change has either made it easier for me to "get away with" more casual clothes than I'd previously have felt comfortable in, or at the very least made me feel better about wearing them. For the first time ever, I bought two zip-up rock band hoodies (thinking that they'd at least keep me warm without pilling), and I was really surprised to realise that they actually look great with my other clothes!
Good glasses (very dark metallic brown wire frames) and sunglasses (Jackie O style, in brown tortoiseshell) have also made a big difference, not least because I don't avoid wearing them, now that I have some which I actually like...
My resolutions for 2014 are:
- Figure out how to dress for summer without spending a fortune or looking like a full-blown goth again;
- Buy some more of those wonderful 3/4 sleeve linen t shirts from Zara as soon as they appear in store, since my three have been worn at least once per week each for the past year;
- Hopefully limit purchases to aforementioned Zara tops and a new pair of Docs this year, because I'd really like to reserve the rest of my disposable income for savings and more books, gigs, and days out with friends...
