Symbol like ‘\propto’ but inverted

Question

I'm looking for a symbol like \propto but rotated 180 degrees (or even better, a symbol like the pink ribbon rotated in -90 degrees) but can't find it anywhere.

Im looking for somthing similar to the following picture:

(again, if it resembles the pink ribbon rotated moreso than an chopped infinity, it's better but anything of this form will do). How could I make one such symbol?

Answer 1

You can use commands from the package graphicx to do the rotation.

\documentclass{article}
\usepackage{graphicx}

\newcommand{\proptoinverse}{\mathrel{\mskip1mu\reflectbox{$\propto$}\mskip-1mu}}

\begin{document}

$A \propto B$

$A \proptoinverse B$

\end{document}
