Outfit for my morning walk! I’m 5’7” and wearing size small in the top & bottom athletic set (I usually wear size XS in AF, but these are comfy as is!) I’d recommend sticking with your true size, no need to size up unless you like them a little less tight. The quarter zip is an XS as well! It might be out of stock so I’m linking a few similar at different price points! LTKActive LTKSeasonal LTKStyleTip
