I would buy 3-5 bags in different styles and colors.
Tote
Sturdy handbag in a cool shape
Baguette (love the Frances Valentine Pia Baguette in patent leather! Lots of fun colors!)
Cross-body
Frances Valentine is the real Kate Spade. Candidly, I like both brands: they hold up very well and typically come in interesting shapes and colors.
I like Hammitt cross-body bags.
Don’t just buy black or brown. Red, lime green, and orange are surprisingly versatile year-round.
