Brazilian butt lift. Bigger pants size?

The size wilp depend on your body shape and the type of buttock lift you are having.  When you are selecting the waist band, your size should be smaller if the fat is removed from the waist.  The butt may be larger, but depending how large it becomes, you may not need larger pants but you may fill out your regular clothes better.

This is very difficult to predict as the waist will be much smaller and the buttock will be larger.  This will also depend upon the cut of clothes you are accustomed to wearing.  I
would search for the board certified plastic surgeon who you feel is
most likely to give you the best results and who performs hundreds of
these procedures each year. I would look at patient reviews as well as
before and after photos on that surgeon's website.Kenneth Hughes, MDLos Angeles, CA

Not necessarily, most patients end up having a much smaller waist, resulting in all of their pants fitting loose around the midsection, thereby eliminating the muffin top.

It really depends on what your desired outcome is. There is a chance you will need a different size pant, but it depends on what you want your end look to be like. Consult with a board-certified plastic surgeon in-person to discuss your options.

Thanks for your question. As my colleagues are saying, it depends in what size of projection you are having and what kind of structure you have. The goal of the BBL is to reduce the size of the waist as much as possible as to enlarge the buttocks depending on the projection the patient wants. If your clothes are spandex they might fit just well, but there no question they would look much much better. Please have an in person or a virtual (Skype) consultation, so you can discuss thoroughly all your concerns, expectations and options, good luck in your PS Journey!Respectfully,Dr. Jaime Campos-Leon
