Type of shirt when jackets are waived…..

Oh so sad : (

Tucked or untucked has been discussed here before. My take is that it depends on the cut of the shirt and the conformation of the rider as to which is the more tidy option. The technical fabric shirts can look very sleek; a polo tucked in can leave an untidy shirt line. YMMV.

well you are right. I will say I have never seen a patterned shirt, and I’d ask the TD before wearing one.
