Thanks everyone. I've managed to find this in the DP sale which I think will look alright (my dress is actually a very dark grey), and I think it would work with jeans and a top afterwards so I won't be wasting money!
Yes the dress is nice, smart shoes and either a colourful cropped cardi or a jacket. I work in a uni lib but would still dress more formally for an interview so if you can find a fitted jacket that matches (or in a colour like red or turquoise) then great but otherwise fitted cardi fine.
most important is that you feel comfy and competent
Dress is fine I'd change the belt, perhaps A bit of colour is always good in an interview so either a coloured card, or invest in some great, maybe slightly kooky, coloured shoes. Helps people remember you.
The dress is fine. Black tights are fine (unless it's summer - which it isn't here!) I think a jacket, or a cardigan would be perfect...I think a black cardigan might be a bit dull...with a grey dress you could wear any colour cardigan that suits you.
Personally I'd go for the grey dress with a pink cardigan, with coordinating jewelry (or just subtle jewelry) .
I've got an interview coming up (yay!) for a university library job - so it's a professional teaching-ish role, I need to look smart, but it is a library and generally that's not the sort of place where you need a full suit. Which is good, because I don't have a suit! So help, please, I'm at a loss...
I've got a very conservative dark grey shift dress (kind of like this but not the jacket to go with it. I don't really like the look of shirts or long-sleeve tops under dresses like that. Normally I'd wear it with a cardigan, so I was thinking maybe buy a nice new black cardigan so it looks smart and fitted - do people think that would work? I can manage heels, so that should help. Though do you think nude tights would look better my normal thick black tights? Or would black trousers and a nice top be better? I could in theory spend a little bit of money, especially as I could use the outfit again for work. And if people think trousers and a top would be better, what kind of top? I'm just not the right shape for shirts that need tucking in.
