Places to Sell/Swap Kimono?

Hi all,

First off, I apologize if this violates rule 2 in any way/shape/form - it's not my intent to try and market a sale on the subreddit by any means. If mods take issue with the content of this post please let me know and I will delete it asap.

A well-meaning family member gave me 2 beautiful vintage kimono that they saw while thrifting and bought them for me because I took Japanese classes in school. I immediately felt guilty because they are extremely under-sized for my height (I'm around 185cm) and I have nowhere to wear them at all (and really no way to store them safely). Ideally I would like to sell or exchange them but I am concerned about being ripped off as the kimono and haori are both very clearly 100% silk. Is there any advisable place to list them for sale where I might not get totally screwed over?
