Medium vs. Large Carly

I plan my bags around my sunglass case, it is huge but I am not willing to scratch or break them. I was looking at Carly at Coach and putting my things into it and the SA said "You really have to lose that case". I can fit a HUGE glass case, wallet, makeup bag, phone, gum and mini skinny in a medium Carly with no problem and it didn't look overstuffed . The medium is really not awfully small.

Here is what's inside my medium Carly:
Coach sunglass case (Which I have to carry up/down, not sideways)
Wristlet
Cosmetic Case
Mini Skinny
A few things in the pocket

That's about all I can carry and still have the bag look nice and not grandma-bag stuffed...still LOVE her though!
