I agree with the top comment. Most often times women won't see the tight abdominal muscles, or slight abdomen veins until their bf% is well under 20% or even 19%. Although with getting there, most often times women will lose their hard earned gains just as fast as they retained them if not faster, with excess cardio, or intense dieting. For women it's a bit of a structured guessing game, and it becomes increasingly challenging (not impossible), the more muscle you pack on. Ladies who juice can recomp like it's nothing, but the natural ladies just have to know how to time feedings, carb cycle better, monitor water intake, monitor trainings according to our monthly Menstrual cycles, train effectively, etc.
Since you stated that you've lost 85 pounds, I take it your weight is somewhere around 135? Yes? I don't know if you predominantly did cardio to lose the weight, or what your body fat is, but your best bet would be to gain as much lean muscle as you can. I wouldn't suggest bulking just because you've done a great job of losing so much weight and it'll probably dissatisfy you to see the weight go up again. So maybe a small increase in calories (maybe 100-200 calories every week?) and monitor your weight gain, and have a rough estimate of body fat, and see how your shaping up in the mirror, etc. And see how that goes. I'd also suggest maybe throwing in an extra heavy lifting day. That's all the info I can give you without knowing more about your training, eating, and daily habits.
