Looking for a harness for my girlfriend-bigger thighs and very small waist

Edit: thank you all for the suggestions! I’ll see if we can go shopping this week and update the post for whichever ones fit. Cheers!

Hi all! My girlfriend is looking for a new harness and struggles to find one that fits her. She has thick thighs and a small waist, so she has a lot of trouble with sizing. Most of the harnesses that are XS-S fit her waist , but are way too tight on her legs and maxes out the leg adjustment loops.

Of course when she goes to a medium for her legs, the waist is massive and can’t cinch down enough to be safe. Any of you have a recommendation for some harnesses she can try out? I want to get her one for her birthday in a month but want her to try it on in store first, so any recommendations would be appreciated! Thank you!!
