Just recently completed 5k and continuing with my Running as I love it. The only issue i have had all along is finding a loose fit, slightly longer length top for Running. I hate the short, tight vests. In the past few weeks I have tried 5 different tops from different brands. They look loose on thr photo then when they arrive they're clingy and horrible. Any advice? It doesn't have to be a branded top,just something that does the job. Thanks.
