I love this thread! Technically, we don't
need any bags - we can simply carry our belongings in a grocery bag or a department store shopping bag. But, as we live in polite society where being put together matters (at least a little bit), that is not practical. I think everyone's need depends on their lifestyle. Years ago, I only needed 2 bags: a school bag and a not-school bag. When I started working, I needed a work bag and a going out bag. Now, as my lifestyle has changed and the things I do and places I go to has increased, I find a "need" more.
Assuming everything is in a neutral go-with-everything color and is appropriate for all weather scenarios (bright sun, pouring rain and everything in between), my needs are as follows:
- Large Shoulder-Carry Work Bag;
- Medium Shoulder-Carry Everyday Bag for all essentials of a long day;
- Small Shoulder-Carry Everyday Bag for all essentials of a short day or a casual evening out;
- Clutch for cocktail parties, black-tie events and weddings;
- Cross-body bag for sporting events, museum trips and grocery shopping (I could just use one of the every-day bags if I had to, but having a cross-body for these occasions is just easier and I don't like cross-body bags enough to substitute them for one of the everyday bags);
- Gym Bag/Overnight Bag (can be one bag that serves both functions);
- Beach Bag.
That said, I have way, way more than 7 bags, but I love them all and won't sell or part with any of them. I have, however, maxed out on closet space, so I won't be buying anymore unless I clear out room for more.
