I don't think it's silly at all, in fact I feel the same way. When I treat myself to new workout gear I immediately want to go use it and take a class. I also find that I am more confident in my workout and will push myself a little hardeer as well. I'm a bit of a fashionista and like to look cute no matter what I am doing, but I do find that a great workout outfit makes me want to show up for myself in that space.
@sotoalyssalol - I AM this!! Clothes can be confidence!! Tennis, to me, was all about the outfit with exercise as a benefit! I would get a new outfit and play my heart out. If I lost, my positive was ' Well, at least I looked good.' HAHA! I think my mental health starts on the inside and how I feel navigates my day.
