Pride month is in August in my area, and to close August out, I've made some button-downs that I've seen IRL in a local store and thought were delightful.
They have buttons in the colours of the rainbow pride flag, and are otherwise just black and white. Subtle! Versatile! Not even really all that flashy or tacky! Completely, totally Maxis-Match. May even do your dishes. (No promises, though.)
Get it here! Meshes by platinumaspiration included.
