It appears you have had massive weight loss - congratulations! Great job doing it with diet and exercise. If you are at your nadir of weight loss (low point) and weight has been stable for 6 months and no other medical problems (heart disease, high BP, diabetes, vitamin deficiency, etc) then you could proceed with body contouring procedures.
You will likely benefit from a breast lift +/- implants or potentially fat grafting in a 2nd surgery to augment the upper pole of the breasts. You will likely benefit from a circumferential body lift (360 degrees liposuction, belt lipectomy and incision all the way around waistline and back to tighten and lift the buttock, lateral thighs, flanks, back, bra lines and abdomen/pubic areas). You will likely benefit from a staged thigh lift as well (liposuction to debulk and sculpt the inner, outer and anterior and posterior thights) and then come back in 6 months and perform a formal thigh lift.
These are long extensive surgeries but they will best deal with the loose skin and irregular contours.
Many surgeons and facilities have BMI cutoffs of 30-35, and while may seem arbitrary, there is some data showing increased risk of complications for patients with higher BMI's. If you are able to to lose more weight, and are not yet at your low point/nadir of weight loss journey, then it is best to wait so you don't deflate further after surgery.
I hope this helps, just my opinion, which obviously does not override my overall recommendation to be seen by a trusted and experienced Board Certified Plastic Surgeon so they can review your weight loss, medical and surgical history and examine you.
Wish you well and great job again losing the weight!
