Hoosier, I am older than you but the things I did was pilates--fantastic for posture, and if you hold yourself better you look taller therefore slimmer and it also did wonders for me for the old aches and pains I was getting.
It was quite strenuose(sp) then I had a bit of a car accident so took up yoga and am still doing that Hatha Yoga that is a good all round practise. I love it and it's changed my whole attitude to life.

I also went and got a free makeover at a make-up counter( not sure if I can say which one but go for one of the better make-up people-I used clinque)I don't use much make up but I had had the same stuff and colours for years.Money is tight for me so I didn't actually buy any but put a good foundadtion on my C,mas list and a few other bits.

I also had a person who did my "colours". You forget as you age your skin tone changes and what used to suit whilst it may still be ok,fresh eyes can really show you which colours look great on you.Rather than change my wardrobe again cost, I bought some scarves from a charity shop and have gradually replaced items in my wardrobe. So you can all this stuff on a budget.

I find it I think I look good I act in a different way.
I am not overweight but do have a tum so I am careful about styles and try to exercise but apart from dance and yoga not a gym person.
I hope this gives you a few ideas.
