I decided that I can wear a big shirt with my black pants to work and make this my new uniform look, however it does not need to be boring or suit-like.
I found the pattern Kerry's Big Shirt from Rag Merchants and picked some colors that I think will be great. The purple one is the first of the collection and goes great over a black tank top or, in cooler weather, over a long-sleeve shirt.
And, as you can see, I had help. The grey one is the second one I created. Both look great with gray or black pants and will wear will at the office.
Pedro looks like he has given his permission.
Looks like a successful project to me~!
