I think the E/W is really cute and I had one for a few months. However, I eventually sold it and bought the M/L flap instead. They both fit the same amount surprisingly because the E/W doesn't have that 2nd flap inside but in the end, I really wanted the classic Chanel bag and I never once regretted my decision. The E/W is cute in that it can be made into a clutch but I liked how the M/L has the double chain and can be worn short and long.
This past Christmas Eve at a party I was at, I wore my M/L of course and some other girl there had the E/W. She came up to me and said she loved my bag and wished she had it instead of hers. Even though the E/W looked really cute on her, I thought something was missing. I think it just looks a bit too long, I dunno.
However, I do think the E/W is very cute in a color. If you already have a M/L though then yeah, you can't go wrong with an E/W in your collection as well. Good luck!
