There are a few things you should know about a momiform. It HAS to be practical and comfortable, but I also really like it to have some sort of edge. Whether it's a little sexy or cool, adding that extra element keeps it from going frumpy. I feel like I've made it my mission to nail down this look so I can feel my best but still run around with the kids.
Shoes are another an important aspect of any momiform, so I try and keep mine either in good shape...or on the newer side. Beat up kicks aren't cute on anyone. I've found that a magic eraser works wonders on the white of my shoes, and keeps everything looking fresh.
Speaking of cool, nothing adds an instant cool vibe quite like a faux leather moto jacket. This specific one is included in the Nordstrom Sale (as well as the adidas shoes!) and comes with a detachable hood, which is perfect for pairing with workout clothes.
Unfortunately I'm not able to link the exact leggings that I'm wearing, but I've linked some options below that I've had my eye on/think would work well with this look. If you are interested in these exact leggings they are by Lululemon. The two styles that I own and highly recommend are the Wunder Under HR 7/8 Tight, as well as the Fast and Free 7/8 Tight II. At 5'3 both of these 7/8 crops are a little longer on me, which I love.
Don't forget, today is the LAST day of the #nsale, so snag whatever you've had your eye on while you can!
