I love an easy sweater and this neon sweater from the Gap just oozes ease. I'm shaking my head right now thinking to myself I always get the same feeling any time I wear Gap clothing. They are so comfortable, which I'm always reminded by my sister telling me "Girl I told you so!" Anything Gap is her basic. :-) The sweat pants are also Gap but sold out quickly and I believe you already know the reason why :-). You can try this legging for a similar comfort and they also have it in blue.
The sweater is selling out like if it's free so if you LOVE, get it! The selection of colors they have are so fun and easy that you can pair it with anything so I decided to pair mine with a leopard scarf (love this brown and black printed version) and a zebra print shoe I've had for many years. I found a point toe zebra print as well as loafers which I think are so cute! Let me know how you plan on pairing your sweater!
