I have the pillow tabby 26 as well as the 18 and I use the 26 way more than the 18. I have the same one as you 💗 the leather is very delicate and even with minimal wear the 18 doesn’t look the best. I would suggest taking your bag to the Coach store to have it cleaned.
I’ve seen the 18 on other people and have tried it on a few times in-store and I feel it works better for my body proportions. Will definitely take it in to Coach for a clean ☺️ thank you 🥰
