where can i buy Linda's swimsuit
cuz i i dont swimsuit in the store

I don't know if you already bought it, but im gonna say it anyways:

pick the store in the map 

you will click the road on the bottom left on your screen

then go to the store and talk to the owner

that's it.... hope it helps!

I was also stuck trying to find the swimsuit. Is really hard to see that little road, hope they add a sign or something in a future update lol
