I have similar body type and the jeans that look best on me are Lucky Jeans Classic Rider for daily wear and Dojo style by 7 by All Mankind for designer/going out. I often can get Lucky jeans from Marshall's/T.J. Maxx for $35 plus tax. Option #2 is to wait for 50% off sale that Lucky Jeans has on a pretty regular basis. They have quite a few on sale right now that are extra 30% off, like this one. I've scored designer jeans for less than 50% off retail from department store clearance, Nordstrom Rack, MyHabit, Yoox etc. My last two pairs were $30-$35.
