Hi Ladies....ok.....here are comparison pics side by side of the LM and LMM. Hope this give you a better understanding of the size. And I photographed these wearing my coat to let you see how generous these bags are. The LMM is not tight under the arm whatsoever....I know that can be an issue with some bag styles but not this one! First up...my LM in dark grey Second....LMM in FUSCHIA!
