Smart 'interview' outfit and work wardrobe for 15 year old Sz 4 to 6

[HattietheManatee]

Can anyone recommend somewhere to buy petite workwear suitable for a slim teenager with personality?

DD15 has an interview for an internship at a prestigious law firm. She has been asked to wear something she feels would be appropriate for interview. If she gets the internship she will need a weeks worth of outfits at very short notice so I'm trying to get some back up outfits ready.

She normally wears oversized jumpers and DMs so doesn't have any smart clothes. She's a size 4 to 6, about 5ft 2inches. I took her shopping yesterday and got her fitted checked blue and green trousers with a bottle green t shirt but ideally need some sort of navy blazer or jacket to tie it all together without looking too formal. I also was thinking of some black skirts and dresses as she can use these for her music concerts anyway.

NB - She hates skirts/ dresses which are any longer than 3 inches above her knee (really!)

Our finances have taken a beating with me going part time so ideally the outfits would be reasonably priced.

Any advice or suggestions very welcomed!

My go-to are slim fit slightly high waist trousers from ASOS (some are on sale for £10- search skinny fit high waist trouser!) and a shirt, with brogues or loafers! Had to get a work wardrobe and cheap, but shirts are easy to find even in supermarkets.

One pair of smart black trousers will do for a week (you can wash and dry over night) and three shirts and a pair of smart shoes will be fine.

15yr old interns done need to wear blazers or jackets - I'm 30 years older and i don't - I'm a skirt and blouse girl.

Warehouse have a sale on and h&m are good for small work shirts. If you get blouses rather than cotton shirts she can wear with jeans at other times.

Maybe return the blue/green trousers and get plain bottoms and then you only need a couple of tops variations.

Black skirt and dress will be totally fine. Fitted jumper or top with skirt. You could go for a shirt if you like but I’ve been a city lawyer for over a decade and hardly any women wear shirts nowadays. Good luck for the interview!
