Happy Birthday something. 
Some wonderful posts here about accepting encroaching age.
This is a well timed thread for me. I've not taken a huge amount of interest in my appearance for quite a while, although I did lose a couple of stone last year (put around a stone back on and am now in the process of losing it again). Saw some photos of myself at a wedding recently and thought 'fucking hell, when did I turn into such a middle aged frump!'
I'm 41.
So... Operation De-Frump has begun! I've been doing a Start Anew September, eating the right food (no sugar, low carb/paleo, no processed shit), no wine [sob] until next weekend and then just moderate amounts of red at weekends only instead of the gallons of white and bubbly I like to glug. I've lost 5lbs so far without feeling remotely deprived (apart from not drinking at weekends, which feels bizarre). I've never been remotely interested in fashion, just wear things which flatter my shape, but I'm realising that I've got to start dressing a bit more wisely and get more of a style. Ditto makeup, as my skin is shit (always has been) and my eyes (best feature) are a bit droopy and hooded. I've always worn makeup, but not a huge amount, and I think I need to invest in some decent foundation and stuff now. Have just hennaed my hair as it was mousy, dull and going grey. I'm contemplating a fringe, but am very nervous about that. I tend to just scrape my hair back as I hate the sensation of it on my face, but that's not at all flattering and I need to find an alternative.
Main thing is I need to tone up. I have a spinal curvature, chronic pain and dreadful posture, and would really love to get fitter and more toned. I was naturally thin for years, eating crap and not exercising, so I don't have good habits in place.
All this stuff costs money, that's the trouble. I'm telling myself at the moment that I'm not wasting money on wine so can spend it on other stuff.
