I have the same problem unfortunately /sob
it is really hard to find things in this size, it usually depends on what brands are available to you and all (like locally or something).
From what I can gather, Bodyline do a pretty good range of sizes, just double check the measurements to see if they're all okay.
Also, Milanoo is a pretty good bet and if they don't have the size you're looking for you can get it made to your measurements.
I hope this helps your friend in need!
If you want to ask anything else I'm more than happy to help
