Lost 11 lbs. but I can't tell the difference?

Hi! I've recently lost 11 lbs. I've gone from 165 to 154 (I'm 5' 3" if that makes a difference). The only thing is, I still look like I'm 165 and my clothes still fit the same for the most part. So how much longer until myself and others can actually tell I'm losing weight? Like how much more weight? Thanks!!
