I am an American visiting Kuala Lumpur on business. I dress pretty casually - t-shirt tucked in jeans/nice travel pants, Adidas Samba sneakers, and the like. Think casualwear from Old Navy, Uniqlo, H&M, etc. I never needed to dress business formal for my job, so I don't really have business formal clothing.

I could buy a few pieces if needed, but not sure if wearing what I normally wear would be very out of place or offensive! Can someone please shed some light on how most women in their early 30s dress in the office?
