Am I Too Skinny for a BBL? How Much Do You Need to Weigh to Get This Procedure.

Hello dear!!
Thanks for the question and provided information as well. 
Unfortunately, without pictures, it is very difficult to give you a proper answer. 
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less. l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

It is difficult to tell whether you are a good candidate or not based just on your measurements. It's best to upload photos or have a consultation with a plastic surgeon to get the most accurate advice. It seems you could be able to receive a BBL but more information would enable me to give you better advice.

            I perform the Brazilian buttlift on thin people quite frequently, and there are very few patients who are not candidates.  I perform about 500 Brazilian buttlifts each year, and this procedure is the most surgeon dependent plastic surgery procedure.  Find a plastic surgeon with ELITE credentials who performs hundreds of Brazilian buttlifts each year.  Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results.
