You may not agree with me when I say that it's perfect scarf weather right now, but hear me out. If you're trying to wean off of wearing your winter coat completely, the perfect way to go about that is to stop wearing it altogether and start wearing scarves instead before you need to pack all of those things away until next winter.
I've been doing it for about a week and it's worked out great. Especially because I don't need a coat in the morning since it's starting to get warm, but if I'm still out in the evening when it starts to get brisk - I've got my scarf in the bag ready to go. Or you could be an extremely well-put together adult and buy a spring jacket. I happen to like my suggestion more.
