My assistant on occasion wears what I believe to be inappropriate office attire. I may be wrong so I figured I’d ask you guys. Are these appropriate ?
Clothing:
Fitted tops
Tops that show midriff when arms are raised
Sleeveless tops
Low cut tops
Hipster jeans or slacks
Footwear:
Push ins like thongs or flip-flops
Open back shoes
Tennis shoes
Fitted tops should be great - a nice, tailored appearance. Do you actually mean "form fitting", as that is something different, and yes, inappropriate in the work place.
I'm betting she's young and dressing young. Midriff baring is not appropriate, low cut is just wrong. Sleeveless, well, people argue this. Here, our dress code says sleeveless is only ok if a sweater or something is worn over it.
Hipsters - if we're talking so low that, um, stuff can be seen, Not Appropriate. If we're talking nice slacks that are cut lower, some of us have body types that these styles really work for so if they're nice enuf, that should be ok.
Flip flops - unless you're a lifeguard, NO. Open back and tennis shoes depend on environment.
If I can find our dress code, I'll send it. I agree with previous poster, you need to have the conversation. You will also need to use a phrase kids have cringed at for years: Appearance Counts.
If there are more people in the office, you can draft a dress code "for everyone", otherwise, I think it's just one uncomfortable conversation.
