The casting itsef was nothing exciting, it was as basic as my outfit! (had to strip off my jewelry ( by H&M)). I got invited and I would not want to miss opportunities like this - if youre ever invited to similar occations and you have time - then my advice is to go. Even if you are insecure about yourself (like me).
You never know what you miss, interesting contacts and media experience.
To be a "real" model nowadays you need other measurements than me.
Sometimes I don't even fit into size 36/4 pants, which always had fit me during my teens.
That's the reason I love seeing clothes on bloggers rather than models, who have to fit he sample sizes of designer clothes.
I wish you all a nice day, take care.
