I don’t know what specific brand Taylor uses, but I can recommend M.A.C. lashes. They’re excellent for beginners, a lot of them have very soft stems (the part that the lashes connect to and sits on your lid) so they’re comfortable to wear.
Some of the more natural ones that I can recommend are #7’s. They’re a bit more on the dramatic end of the “natural” lashes, but they’re a sprayed design so your natural lashes can peek through the falsies. So beautiful. #33’s (also by M.A.C.) are insane. They seriously look like you don’t even have lashes on and they also have the same clear, very light stem so it not only looks like your natural lashes, it feels like it too.
Sidenote: Duo Lash Glue is the best glue to use when applying falsies.
