I own both and wore them for the same amount of time. I like Jaanuu better. It isn't as boxy, the v-shape neck isn't too low so people don't see my girlies when i bend down, and the quality feels good on hot days and cold. Figs are thin, runs small for me, and are too expensive for their quality feel. Also, jaanuu is great for apple shapes. It runs the right size and enough space for my stomach enough that the legs part doesn't look baggy. I gave my figs away and all I own is jaanuu now :D
I wear a small in scrub bottoms in pretty much all brands…but I do find the Figs bottoms, esp the joggers and the Yola 2.0, to be on the smaller side. I think it’s just the more fitted style, which I don’t mind, and they aren’t actually tight on me, just more form fitting. With the tops, it’s the opposite, I think that the Caterina top runs a touch big. I’ve been tempted to get those New Balance shoes, just don’t like that they have a big Figs logo on them, and of course worried that they won’t fit. I hate sending things back.
