It's very easy to get it wrong. I saw that even one of the Purseblog writers was confused https://forum.purseblog.com/threads/jackie-bag-is-back-for-aw20.1024086/
Basically, the Jackie (introduced early 1960s) has a gusset. The original Bouvier from the late 1950s (I prefer) does not.
Not to be confused with the double handled Bardot bag!

2020 Little Jackies relaunch
Thank you so much! Honestly I was fairly confident about that but you're right - I've seen a few purse blogs mislabel them and I started to go a little batty going back and forth haha.
