Interview advice

Casual dress might not be the best idea. I would wear a suit and tie. I have interviewed at 3 companies that have no dress code (very casual environment, everyone wearing jeans/shorts and tees) and wore a suit and all the other interviewees did as well. (This was in the states, I see your in manchester so things may be different across the pond)

In my experience, even if the office has no dress code and is very casual, you should still wear a suit to the interview. It will show you take this interview seriously enough to dress for it.

Basically, if all the other interviewees wear suits and you dont you are not going to look very good compared to them. If the inverse happens and you wear a suit and they dont well you are going to look sharp and look like a serious candidate while they wont.

However, you could call the office, speak to the secretary and ask her what interviewees normally wear if you are still unsure.

my interview is tomorrow so any quick replies are helpful their site is

oops just saw that. you might not have time/resources to get a suit on such short notice, but the advice below would still be helpful for the future

If you do not own a suit, you should look into purchasing one because you are going to need it. Buying a suit and everything that goes along with it is expensive, but is a worthwhile investment in your self.

Below is quick run down of stuff Ive learned about professional dress:

Charcoal is a great first suit color to buy because it can be worn to any event (interviews, weddings, funerals) and also gives you a good range of shoe/belt colors to wear with it (it will look good with brown or black shoes which makes it very flexible). Finding a suit jacket that fits off the rack (OTR) is a challenge so you will probably need to shop around.

Get a solid color dress shirt (white/blue are pretty great. I prefer white). Dont get one with french cuffs (those require cufflinks, dont need em)

you have a lot more freedom on your tie so I would probably get some help with the sales associate to pick one that looks great with your shirt/suit. Solid ties are generally more formal than more elaborate ones. I like using the four in hand knot

I probably wouldnt wear a pocket square, but if you do make sure it compliments your tie, but does not match it

The rule of thumb on sock color is your socks should be a shade darker than your pants. Make sure you get dress socks and not regular style socks

Dress shoes are pricy so be prepared to drop some cash on them. wear dress shoes that lace (not loafers, those are too casual). I like brown shoes over black because you can wear them with more things. oxfords are pretty popular and a pair of brown cap toe oxfords would look great with a charcoal suit. I like the look of wingtips as well. Pick up a shoehorn while you are at it, it will help your shoes last longer.

your belt should be close to the same color as your shoes (they dont have to match exactly, as long as they are similar)

generally since interviews are in confined spaces you dont wear cologne since it can be overpowering.

If you have prints of your designs/other work you might ask some other designers/google what they use to carry them in (probably some sort of leather portfolio thingy). I probably would not use a backpack
