Where can I buy graphic T-shirts that are oversized, and long?

[OuchyCyst]

Looking for large baggy t-shirts (not plain, but with a graphic or pattern) that I can throw on for dog walks over leggings. I’m a size 18 and would like them baggy and long enough to cover my backside. Lightweight cotton for the heat of summer, if it ever happens! H&M oversized Ts all have reviews to say they are not really long enough. Thanks for any tips ☺️

Just realised this might be the wrong place as what I am asking for is not particularly stylish, more practical!

Uniqlo mens.
The XL fits my over 6ft well built son

Size 18 go for xl unisex and search graphic t shirts in Etsy. So many cotton printed tops to choose from and you can also support small businesses.

Not popular on here but shein do amazing batwing style ones usually with pockets that are perfect for over leggings walking the dog.

Yours has some, some are bit plain but fit nice.
