if you have enough girlfriends, you can probably go on alibaba and get them custom made. you just need to find the factory that makes the version with clips, and you ask them to use the chamois you like. if you order 10 (2-3 bibs a person, 10 is probably not hard to sell for something that's life changing like that). Would end up costing you less than AliX too, because a lot of the price you see is shipping. Free shipping (ofc) simply means the shipping price is included.
And you could custom the rest while you're at it.
you can probably order just one or 2, btw, but then shipping becomes exhorbitant as a share of total cost.
