Where do i get umbrellas in sims 4?

@ForiverSimmer, in addition to what @annalw2000 said, you can look for objects by room and select either the kitchen or the dinning room and then click on the bowl of fruit labeled Misc. Decorations (I know it is odd! 😃 ) and then scroll down until you find the umbrella stand. 🙂  The bowl of fruit in the kitchen is on the counter and the bowl of fruit in the dinning room is on the dinning table.

Once you place your umbrella stand where you want it (probably not in the kitchen or the dinning room! 😇)  you can have each sim individually choose their umbrella by clicking on the stand.  And if you decide to go with another style of umbrella, you can do that on the stand as well! 

If you ever need to find items in a new pack easily, I usually go into build mode and use the filter on the right hand side above the pictures of the items you choose from.  It says filter items and has a little triangle next to it.  If you click on the triangle you can then choose different ways to filter your selections .  In this case you can click on "Packs" and scroll down to the pack you want to concentrate on (like Seasons) and then you will only see items from the pack(s) you select.  This helps to find new items that can get lost in a large menu of older objects! 😉

Happy Simming! 🥳
