Bib shorts that don't ride up

[deluz]

I have short legs (30.5" inseam), my thighs must be skinny because all my bib shorts ride up and I keep having to pull them down during a ride.
I have Q36.5 Dottore and Gregarius. The Dottore stay in place better but I cannot afford them unless they are on sale but they are the best bibs i have used. Neither of them have silicone grippers. I used to use La Passione and they were pretty good but the last pair disintegrated prematurely and it looks like they are going out of business. Any others to consider? Budget is up to $250.
