There are times when I find the opening to be frustrating, but deep down I know that the 30 would have been too big.
Yeah, I'm starting to feel the same. I wanted to love the 30 because it's a better "deal" with such a small price difference, but I think the size would prevent me from using it as much. It definitely had a very casual vibe on me whereas the 25 was more versatile. I plan to wear it mostly cross body since I have a 3 year old and a baby!
