I wear XS in old navy & 0 in their jeans. The grey joggers are XS but the blue are small. I ended up taking home the small for a more baggy fit.. up to your personal preference how you wang them to fit. Can’t believe these new Old Navy arrivals! The OG loose jeans fit me like a mid-rise and look, feel and fit identical to my AE pair 😱 and the floral jeans remind me of my FP pair.. so many great looks here for total steals! I love how long the white tee is — booty coverage so you can even wear with leggings! The joggers are THE BEST.. just wait until you feel them. You’ll want every color! And the pants at the end are technically their activewear so you can wear them casual with sneakers AND wear them dressed up for work. Absolute staples! And sooo comfortable.
