The petite girl fashion is common within different cultures, but the go to (default) pairing (and maybe my personal favorite) may be the skirt and jacket.
The style of jacket worn maybe a jacket over a shirt with an over-sized blouse or a jacket and skirt combination.
For instance, a powerful outfit to me is wearing a mini-skirt, with an oversized blouse, a fun or neutral jacket, and some accessories like dainty jewelries.
While oversized is great (I personally love oversized clothes) you also don’t want your clothes to be so big that it makes you look like you are drowning in clothes!
