The Yacht Collection (11 items) | greenllamas: Sims 4 CC by greenllamas

The Yacht Collection (11 items) | greenllamas Sims 4 adds a set of wavy, long hairstyles that look like something a rich Sim might wear on a yacht. There are 11 different hairstyles in the collection, ranging from loose waves cascading down the back to side-swept styles and a few with braided details. The hairs come in a range of natural-looking colors, like various blondes, browns, and black, and some have subtle highlights.

As far as I can tell, these hairs work fine with the base game and all expansions. If you're looking for some elegant, feminine hairstyles for your Sims, especially if you're trying to make a wealthy socialite or just a Sim who enjoys the finer things, then this set is a good choice. The "pretty rich" aesthetic the creator described is definitely there. Just be aware that these are all long hairstyles, so if you prefer shorter dos, this isn't for you.
