1 week post BBL what kind of pants can I wear?

No specific protocol for garments after surgery is recommended; ask the PS who performed your surgery what he/she would recommend. I ask my patients to a wear compression garment for six weeks to help obliterate dead space and reduce the incidence of fluid collections. Hence loose fitting attire such as thin cotton leggings would be reasonable.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA 

I recommend my patients to wear loose clothing like dresses for 2 weeks after surgery. Consult your surgeon since each surgeon has a slightly different post op protocol.

Hello dear!!
Thanks for the question and provided information as well. 
Based on the recommendations for my patients 3 weeks is the recovery time I advise them, it also will depend on the type of work you do when you return to your normal routine. The post op instructions are really important to make sure the healing process is fulfilled. I recommend dresses, comfortable clothes, a compression garment for a 3 week period,  however I suggest you also consult with your surgeon for any additional information.
Good luck :)

Hello, thank you for your question. As long as your work wear doesn't compress the treated areas you should be fine. If possible, wear a dress. I advise my patients to buy clothing 1 size bigger for the post-op period. The post operative period is the most important, as this is when the freshly grafted fat is "taking root". Take every precaution to keep blood flowing to the area. Good luck to you!

Hello,Thank you for sharing the information, it is a pleasure for me to answer your question.
I recommend wearing comfortable clothes, apart from the girdle, for 3 weeks, you should take the recommendations of your plastic surgeon.
I hope this answer will help youMy best wishes for you...
