I'm trying to compile some information about conference t-shirts. If you have a shirt from a conference and know the make and model (e.g. Next Level Apparel 3600), I'd like to add it to a spreadsheet. My goal here is to have a reference for "I have a shirt from <conference> in my closet that I like, can I also order those for my own event?".
I'm aiming to be descriptive rather than prescriptive here. The first time I ordered shirts for a conference, I didn't have much of a reference point and recall asking the print shop I was using to recommend "whatever high quality options you have". That wasn't a bad approach per se, but knowing what blanks and cuts work well is probably a better starting point.

@jonafato I will absolutely pull some of my favorites and try to get you this info.

The best ever was that Zen of Python shirt from 2017, but I'm partial to a few others.

@pathunstrom Thank you!

Yes, I liked that blank and tried to order it once, but my print shop couldn't get it through their usual distributors, so it would have been prohibitively expensive. IIRC the one I have is a District Clothing blank, but I'm not 100% sure on the specific cuts that were used.

@jonafato I do know the slightly pricier Bella and Canvas blanks and District have been the most reliable (B&C also makes some extremely cheap feeling blanks, so I definitely need to find them to see if I can get the particular model)
@pathunstrom I appreciate it. My end goal here is basically a list of conference name + year -> links to the specific blanks used because (as I'm sure you know) quality within a product line can vary pretty wildly. I'm definitely willing to do some leg work to track down specifics via tag info, etc. One of my challenges here is that I usually remove tags almost immediately, so what I know right now from my own closet is essentially what I've ordered or specifically noted upon acquiring a shirt.
@jonafato PyCon AU has used AS Color “Staple (5001)” for straight cut, “Maple (4001)” for fitted. They’ve also used “Wafer (4002a)” as a semi-fitted in the past, but haven’t for the last couple of years. Let me know if you want other details
@freakboy3742 This is perfect, thank you.
