There's nothing that screams "junior" more than a graduate dev dressed up in a suit awkwardly posing for a LinkedIn photo.

Seriously, stop it, and stop listening to whoever tells you to don a suit so you're taken seriously. Maybe in marketing, HR or finance - but that's not how devs think, or hire people.

I do it cause I be swagged out in my Italian Merino threads

@Almondsauce it is a matter of personal style. Personally whenever I go to the office I wear my suit. And not a stock suit from suit supply or whatever. A fully customized suit that fits me like a...well, armor actually. To be fair I look like a Mexican drug lord that way but people do take me more seriously and I had the pleasure to have several going outs with people that land contracts...

@NeatNerdPrime Hey if you rock it and that's your style, you do you. That sort of thing shows through in a good way.

That's a world apart from an awkward looking grad who's clearly just popped on a suit for a photo in the hope it makes him look more employable though.

Funny, I just wrote yesterday in an assignment a recommendation to show up in a suit for job interviews even if the job doesn't require a suit.

@Nanos the undertaker, what a legend! Suit + leather trech coat is my winter outfit.

I think it is totally fine to look junior if you are junior.
I like an awkward stock suit way more than a dirty t-shirt. I will clear very fast that a suit is not needed, but I also wear a suit if you come to me for an interview. You might call it stupid but I call it respect. A jeans/dress pants and a button shirt also works.

But I'm old, so maybe the eorld has changed and I'm stuck in the old ways.

I have exactly thebphoto you mean in my head.
However I think it's more of tzebpose and style of the photo than the suit.
Professional business photoshoots create great photos, evem for young people in average fitting suits.
