For our Money Diaries series, millennial women across the country let us look at a week of how they spend money. For the end of 2016, we wanted to go a little bigger. Rather than just asking women what a normal week of purchases looks like, we were curious about the not-so-normal. Namely, what was their biggest purchase of the past year?From houses to grad school to designer purses, we got 21 women to get honest about their big-ticket item of the past 12 months. They let us know why and how they bought it — and if they have any buyer's remorse. Interestingly, the largest purchases weren't necessarily from the highest earners. Another trend?
