I'll be honest. This all look HORRIBLE because I have absolutely no idea what I'm doing.
I have very little items that could be considered "formal" and I don't really know how to pair them
Things to consider:
The weather is HELL right now. It's boiling and too hot to cover up, having to wear a blazer would be an absolute nightmare. Who even invented summer????
I don't own any formal bottoms, both pants I'm showing are denim.
The job isn't for a company per se, it's a private psichologist office for children with special needs and the position I'm interviewing for is educational monitor. So I also kinda want to look a bit soft and "fun" to work with children. BUT that is also theowing me off because I don't know how formal I should actually look.
If I look uncomfortable in all of this pictures it's because I am. I don't know how to dress
Edit: what is wrong with my bra???
Also, I OWN AN IRON. I'M SORRY. My interview is tomorrow, I was just trying the clothes on 😭😭
Edit 2: I already went to the interview and it went great, thank you all for your advice and tips! I'm gonna lock the comments now. Thank youuuu byee

I'm about to leave guys, wish me luck.
I took your advice ans covered the shoulders, gave everything a good press, brought the bra up a little bit, did a soft and natural makeup look, a dainty necklace and my matching handbag (and resume ofc) and I can't decide if I like the scarf on my hair or the bag better but, oh well. I'll let you know how it went, thank you all for your advice, kind and harsh words alike
Edit: GAT THE JOB
