need sofa/couch cover help!?

Hi! i have to admit i am very clueless about sofa covers, and i need one to cover this hideous floral couch i got second hand from a family member for when i move out! where do you buy such covers? is there a good website with lots of color options? also, are there different sizes? my sofa isn’t very large (sits two) and kinda has an archy/wavy shape (to best explain it lol). please help! thank you!

Surefit and JC Penny are 2 of the better sites that have a lot of selection and they explain how to use a slipcover pretty thouroughly..but you can occasionally find them on sale at discount stores like Marshall, TJ Maxx, and Ross..also since your couch is a two-seater it would be considered a loveseat (much shorter than a couch) and they are typically between 50-65″ wide.
you can go even cheaper if you are a little creative and use a sheet or a couple of yards of fabric, it won’t look as finished as a bought slipcover, but if that’s not important, then it’s a good option..
