It could be a particular bag, or just a certain bag feature. I'll go first!
- Heavy bags: I've realized that I need my bags to be under 3 pounds or else I won't carry it. It'll get even heavier with belongings inside and cause shoulder/arm pain! This is especially important for totes, which is probably why the Longchamp Le Pliage is so popular.
- Too small bags, e.g. super mini bags/WOCs: The Gucci Super Mini bags and various luxury WOCs seem like good value at first, because they're a lot cheaper than the actual handbags. But on the occasion you need more than a phone, card holder, keys and lipstick, they're not that practical. I still love and use my WOCs, but I wouldn't recommend them as a first designer "bag" for that reason.
- Strap material: The super mini bags/WOCs with a full metal chain strap can be really uncomfortable for me. These days I ensure my bags have a leather portion in the strap.
- White bags and SLGs: I ruined one white bag with colour transfer and that was enough for me...I went to multiple cobblers trying to see if I could get it out but no luck
