Interview outfit

[InterviewHelp]

Ive got an interview next week for a healthcare assistant job at a hospital.

I've got some slim fit black trousers and some low black heels.

I was thinking of getting a blouse and a jacket to go with them, but have just put the trousers on and they are slightly too tight thanks to holiday and half term they're wearable and not noticeably tight, but not as comfortable as last time I wore them. So I'm not sure whether I'd be better just buying a dress?

Any recommendations for blouse/jacket/dress would be wonderful. Not got a massive budget but I can afford more next type prices rather than primark, although the cheaper the better really.

I'm 5ft5, size 8-10, carrying a little extra weight on my hips currently, pale skin, light brown/gingery hair.

Thank you!
