My Method

[TheBoyWithTheBelly]

Here is a more in depth study of how I make my belly.  

Picture 1
Has everything I use to make my belly.
    An undershirt(one size larger than you usually wear).
    Two belts(do not use belts that have a swivel buckle the weight will eventually rip it out.)
    Weights(Optional but they add a sense of realism, they make me waddle without acting    
    A pillow(Is the filler and determines the size of belly I use a travel pillow to make my belly smaller like a real pregnant belly.)

Picture 2
Placement of the weight is crucial. My two 5lbs weights are placed horizontally between my hip bones and as far down as the pillow will allow.

Picture 3
Strap the pillow and weights with belts (one above and one below the bump) and loop them as close to the small of your back as possible. I find that this simulates back pain well especially when I do chores.

Picture 4
Pull and tug the undershirt taught and tuck the excess and you have your baby bump.

Picture 5
Accessorize. Breasts, butt pads, and maternity wear are optional but this study is for a mpreg belly.

This method takes some trial and error but I hope this study shows you the basic of how I make my bump.

Thanks for this! Your method looks so good, and I've been looking to shake mine up a bit for a while now. I'll have to give this a shot.
