I don't know what it is, but I am completely loving this outfit! I absolutely love stripes (because who doesn't???) and I really like this black & white tank with the red cardigan. This was my perfect "mom outfit" for brunch, the park, and hanging out with the family.
Here are my full outfit details:
Merona Striped Favorite Tank (I sized up for a more relaxed fit, wearing a medium)
Mossimo Boyfriend Cardigan - old, similar here on sale for $19 (reg $28)
