Thank you for your inquiry.
Generally, we recommend matching items in the same color.
So, in this case, the color is to match the yellow Miko S,
We recommend a shoulder bag in the same color, off-white.

Also, regarding the thickness of the shoulder parts,
If your bag is heavy, choose the thicker one.
If you are lighter, we recommend the thinner option.

I think that especially for small bags, a thinner shoulder strap looks better.

So, in this case, I recommend the regular off-white (25mm).

Finally, the leather shoulder part is 20mm wide.
So it's recommended to put it in a small bag.
Of course, it is also recommended for micoS 😌

I tried adding a leather shoulder strap
