Does 'edgy' simply mean evolving / having your own distinct sense of style as opposed to dressing like a goth etc?
There are lots of posters who want to 'blend in', 'not get it wrong' or 'dress to be invisible' (in the sense that no one will pick them out as too flamboyant or too badly dressed)
I would say the vast majority of posts we see on S&B fall into this category 'is this dress suitable for a wedding' or 'are these (average) trainers too crazy for me, i'm 40' etc
And then there are some posters who have a v well evolved style. They dress to different principles than fitting in.
They are all individual & you couldn't say there's a unifying element apart from an understanding that all clothes are a statement & reflect something about us & our personalities.
Dressing in the least stylish way is as much a decision as dressing up to the nines
I suspect by edgy you might mean 'with personality or indivuduality. This is harder than putting on a goth or rockabilly or rocker uniform but it's v rewarding
It will require you to start picking things simply because you love them. That initially takes courage as it's nailing your colours to the mast.
Start by looking, looking, looking - real people you come across, tv, films, books & online
Start small - buy shoes or a bag or a jacket that really fills you with joy (not it's fine & it won't draw any attention to me)
Keep adding to it - make a wish list, take photos in shops etc
Be brave!
