I think everyone has an outfit that they can wear in public, that is just super relaxing so I was wondering what yours are? for me mine is my navy work-out leggings, white tank top, a thin gray sweater and green hi-top converses. I don't usually wear it but it's holidays for me and I see no reason why I need to dress up.
These low loose AE jeans, a black leather belt, low rise white sneakers from h&m (ridiculously comfy =D), a plain white tee, and this AE popover which as much as I hate some designers for pasting their logos and names all over hoodies I have to admit that is the most comfortable sweatshirt I have EVER worn therefore had to buy it. <- ridiculously comfortable but easily wearable to even possibly a casual party and being fine =)
Well if I'm just at home, I wear these realllly comfy old Soffe shorts I have, they're so ratty haha. (Also, I sometimes wear them out if I'm lazy :P) And a tanktop or old tee shirt I got from like, an activity or something.
If I'm going out and am really tired/lazy/not going anywhere important, I'll wear leggings, a big cardigan or pullover, and sneakers. Or maybe some flannel. :D
