I lost 20 pounds after having my baby. I'm pretty happy with my size i just need to tone up a little more. But with my weight lose my husband has offered to take me shopping to celebrate. (I have had a lot of trouble with weight in the past). I'm at a 13/14 (gotta a lot of butt and thigh), if I lose more weight or tone up a littler more will they be able to alter my jeans? My goal size is 9/10.
