I tried the short slipshorts and they absolutely work. The rise is approx 8.5- 9". Highly recommend them.
I got them this weekend and wore them under a pencil skirt and a dress. Stay put, the legs don't roll up and they and are very lightweight and comfy. They also come in a darker brown and a blush along with the usual 'nude' palette.
I did size up to accommodate my thighs.
