Casual shorts for wide hips

Something I have struggled with for probably the last 8+ years is finding higher quality weekend-type shorts (tasc, lulu, vuori, etc.) that fit lower bodies with bigger quads/glutes. So many of these brands seem tailored only for guys with a BMI of 10, quads as round as a child's bicep, and an arse flatter than cardboard. I'm 6'0" 223, so admittedly I'm overweight, but time after time I either look like I'm wearing boxers in a L or a parachute in an XL. None of these higher quality brands want to put a simple gusset in the crotch to let me slightly open my legs or stride out for a simple walk/jog.

Has anyone found a nice casual pair of shorts, similar to the "weekend short" that tasc offers, where the leg doesn't taper like a pant leg? TIA.
