If you're anything like me (sorry about that if you are), then you'll probably want to collect everything when you play Stardew. Or, perhaps, you just really like clothes. Really like clothes. In either case, I've got the guide for you! This guide will contain a list of every shirt that can't be crafted, and will cover the methods of obtaining said shirts as well!

The items in this guide can be almost always obtained in one of two ways. Either via character creation, or via the Oasis

Character Creation
When you start a new save for the very first time, you can choose your shirt. The number on this page is conveniently the number of the shirt's ID, which comes into play later. Since you can only get a shirt through this method once, you can't just repeat the process at the Shrine of Illusions or something similar, instead you'll have to either just pick one and use method 2 or have a friend create new characters repeatedly to give you new shirts. I don't recommend the latter, however, as it's both tedious and unnecessary.

The Oasis
Every single day, from Spring 1, Year 1, Sandy in the Oasis will sell a random shirt (not any from ginger island, though). This shirt can be any other shirt in the entire game that is otherwise obtainable, and even includes four exclusive shirts found only at the oasis. All shirts are sold for 1000G each, so it can be a bit pricey, but this is the only other way.

Sandy's wares can't be checked in game without visiting her shop. This means you'd need to buy a bus ticket every single day in order to scope out her shirts. Alternatively, you can load your save file into an external analyser such as Stardew Predictor and search the shirt you're looking for by the ID listed here - and that will tell you when she next sells it.

Random Cosmetic Drop
Upon doing a variety of different things - such as panning, breaking crates or killing enemies, you may recieve a random cosmetic drop. The shirts marked as only obtainable this way were previously unobtainable and are now *only* available through this random pool of pretty much every cosmetic item that exists. Consequently, they're hard to get - but fortunately, i've included their ID's in case you feel the compulsion to obtain them through "less fair" means.

Other
You can recieve a unique shirt through opening Mystery boxes, and you can also obtain a new variant of the basic pullover with a sprite difference through the Desert Festival's Dress-Up booth - but only with a male farmer. These shirts have no other obtainable means, but aren't worth dedicating their own section to.

I hope this is useful to you similarly minded completionists out there! I created it mainly as a referance for myself, but I thought it'd be helpful for other people too so I turned it into a guide. In any case, thanks for reading, and especially all the way down to this bit!
