I had this idea in my had for a while. This hat is 100% compatible with all Maxis hair. but may clip with custom hairs. That’s why I highly recommend downloading hat slider made by Redheadsims-CC. My hat was made to work with or without this slider, but with slider you will have more versatility when using CC alpha hairs.

CC info:

All below mentioned CC on the sim made by me:
Sunglasses
Earrings
Necklace
Romper (recolor of Sims4Nexus romper)
