When I'm feeling meh I always find that a really good long invigorating scrub at my face with my exfoliator followed by moisturising as usual improves my complexion instantly and makes my make-up go on smoother.
Throw in a large vino, a dress that you know you look good in and some feelgood tunes as you get ready and I reckon you'll be right .
I second the glass of wine and music when getting ready.
Not sure if this is any help but I have my hair dyed red and find that when it's at it's brightest I have to be bolder with my make up than I would expect to balance it out IYSWIM. If nothing else I find darkening my eyebrows and extra blusher 'lifts' the whole look. Of course this may just be me!
Thanks girls. I still felt like shit and to be honest it ruined my mood so didn't feel I looked good even in my knock out outfit Had a huge row with dh last night when we got in and didn't sleep so now feel worse. Going to start a whole new thread as its more than just the cold making me look old and tired
