Really, it's what's comfortable for you. Once you get used to them, I think you may come to really like them . They tightness around the thigh feels rather "supportive" and it's best if they are tight enough to have few wrinkles under you knee or thigh and not sagging down in back when you sit in the saddle. A belt can help with that.
If they are on the tight side to start with, they will stretch out where needed and stay firm where needed. Don't worry about how you look. You will look like an equestrian, and surely very handsome.
