Loose skin help.

Hey so I’m planning on loosing about 60lbs by December for a cruise. But something that’s holding me back is loose skin.

Most of that fat is in my stomach and I don’t want to be walking about in a bikini with saggy skin.

Does anyone have any advice how to help avoid loose skin or if you’ve had skin tightening surgery how much did it cost and how did it go?

Any help is greatly appreciated! Thank you!
