Do you have a vintage 'archive?' You know what I'm talking about - that box under your bed filled with vintage pieces you simply cannot part with. I've heard about archives of all sizes over the years. Even met a guy who had an entire vacant house filled with vintage items he collected that just, weren't, for, sale. To anyone. Ever.
I think this is a good practice. We all follow the trends and the #feeds, but the key to style is to be yourself. There's such a sense of over-identification anymore and that's basically, well, unoriginal. Collect and (hopefully) wear whatever you want - even if it's too small or too big for you.
