You have to be really comfortable in your skin. You have to start with being in love with you are, with who you've become.
I was a dumpy teenager. My mum was a model and was all about looks, so I rebelled by going goth. It took me years of peeling back the onion to finally stop using make-up as a mask and feel comfortable in my skin.
I absolutely get more comfortable in my body and my skin as I get older, more than when I was in my 20s.
