Compression advice

I had a full TT, MR, and lipo. I'm 14 DPO and starting compression garment after being in bandages and binder since surgery. I took my garment with me to the Dr. Today. He liked the compression, but didn't like the sides because he was afraid it would create lines in my flanks where he performed lipo. He was wanting a smooth SPANX compression. I just put lipo foam in when I got home, but my Dr. Didn't seem to know what lipo foam was when I asked him about it. Do you guys think that will be enough to keep skin from rippling or should I order a smooth compression garment like Spanx or Marena? What causes the ripples anyway?
