Please share your opinion with me! I´m attracted to PS 1 bag. I´d really want a bag mostly for everyday wear but every now and then for special occations also. Do you think PS 1 medium (12.5" width, 8" height) would be too large for evening wear? I know there´s also a small size available 8a messenger style) but was wondering if it might be too small after all. Please tell me what you think??
