Like others here I'm always looking for the perfect insert or liner.
For the Pico and for the Bolide the MaiTai are the best and almost only choices. The Hermes silk fourbi I love - better than the herringbone canvas which I had and sold when I got the silk- they are beautiful, lightweight and cheerful- as well as functional.
The chameleon is good for a Constance.
The D&C are perfect for a GP or longchamp or Hermes canvas bag.
The rue paradis is nice for my soft Kelly 28-
For Birkins I use the large silk fourbi or the MaiTai
The 40 cm D&C I use for a very soft 40B I have
The 30 MaiTai insert works for a soft 35 Kelly too
I have 2 rue paradis - I may add one more- they are quite nice
Thanks for your opinion
It gives a lot of direction about choices!
