The clover dress could work, that has shamrocks on it: https://villagerdb.com/item/clover-dressMy nook shopping had the Shamrock rug today. It's actually cute but I don't think I have a place to use it. I want to grab a couple of the Shamrock sodas and one of the Shamrock hat just so I have something to wear on the day. I don't like the look of the Shamrock suit so much though, a shamrock dress option would have been nice.
it should be in the Able Sisters for spring/summer, if you're in the northern hemisphere.
