I'm coming out of rather a dark period, where things have been quite difficult and I have been quite depressed. Everything is starting to look up now, and I'm starting a new job next month. I look an absolute state at the moment, so I need to give myself a little makeover though before I start!
I have never really known how to dress myself or how to do make up, what to do with my hair etc. I have no confidence about how I look, I have always been a hopeless case, never "put together" in any way. 
I'm very overweight and about a size 18 - sounds bad but I've lost four stone and planning to lose 3 more. Work wear needs to be reasonably smart but not necessarily very corporate. I'm quite short and stumpy. Flabby arms which must remain covered at all times!
Hair is thick and can get quite frizzy. Skin is pretty good for my age but I have never known how to do make up properly. I prefer a fairly natural look but want to look like I've made an effort.
I have a cut and colour booked in at the hairdressers (mainly to hide some bits of grey) and I have just bought some new glasses.
I really want some advice on how I can make myself look professional and presentable. I'm going into a senior role, and although I know my stuff, I also know that people make judgements based on appearance, so I want to get first impressions right.
So, please help this complete dummy sort herself out and look a bit better!
TIA!
