I am lucky. I had 'relatively' slim arms and legs. My weight was in my boobs and tummy. I now have saggy boobs and wrinkly saggy tummy. However, my skin is just like my mums, who had 3 children but not much weight gain. Her tummy was increadibly wobbly, so I would have had the horrible tummy anyway, as I too have had 3 children.
People hold their weight in different places. Some have huge bottoms and thighs and they tend to have really saggy skin at the top of their inner thigh. and the back of their legs can look crepe paper like. You can have an inner thigh lift but it is an extremely painful 'lift' proceedure and does not give great results anyway.
If you have a very fat face with a huge double chin that means there is no difference between your jaw line and neck, then weight loss can look like jowels and a lower face lift is the only thing that can help.
Other people have chunky upper arms and the weight loss can lead to huge flaps of skin that flap about when they move their arms like a flag. You can have this cut off but are left with long scars that are impossible to hide.
With the upper arms it is very hard to hide in the summer or if you want to wear a strappy dress. With the legs the stretched skin can be quite thin and when it rubs together it can get very sore and even split.
With the tummy it depends upon how much skin is left. A lot of skin can hang down like an apron over your pubic hair and even onto your legs. I am not in that position, thank god. I just have very wobbly skin on my tummy that does fold over but only by an inch so you can still see my 'bits'.
If you wear trousers or a more fitted skirt you can see a roll of fat/skin - my friend calls her's her 'mummy handbag'. However, you can wear very firm fit huge pants to hold it all flat and smooth to give a better line.
Of course you can also have a tummy tuck. Depending upon how much of a fold/flap/apron of skin there is, depends upon how much of a tummy tuck you have - mini, full or extended. A mini tuck is just about 4-5 inches just above your pubic line. A full tummy tuck is across from hip bone to hip bone. An extended tummy tuck goes all around the body.
I will most likely need a full tummy tuck but until that time, I will be using Spankx.
Now - do you think I should give that detail to people if they ask?
