Just wanted to add some thoughts to this thread on my recent insert purchases. I received my SO Swift Birkin 30 at the end last month and knew I would want an insert for it, she had a little slouch right out of the box which I don't mind but I don't want her super floppy. I have the new version of Mai Tai in my B35 and while I still think the pockets are pretty useless, it doesn't fold over anymore so to me it's more of a liner but it's sufficient. I have 7rP for a 32 Kelly Sellier and a 35 Kelly Retourne and the fit is perfect but we all know, the price is not so friendly.
I started by ordering the Mai Tai, friendlier price point, new design and I hoped it would be fine. It is not good for slouchy, very soft leather. It's too long for the bag, I had felt this way about her old model in my K35. It pushed the sides out even though it has no rigid elements to it. I was bummed but I'm going to give it to a friend with a more rigid leather and see if she likes it.
Then I ordered 7rP in Khaki. I love the color, it's a great green. The fit is excellent so while the price kills me a little, you can see it makes the bag stand up gently without any bulges. I normally store my bags with their liners in them but I won't be doing that for this one. I'm almost finished renovating my master bed/bath and I had a cabinet built for my bags where they can all rest on their backs. I find that is best for keeping them in shape. If only I could get in shape lying down
Photos are labeled for which insert is inside them.
