I nominate white, off shoulder tops as this summer's "it" top! Not necessarily the one I'm wearing, but any number of tops that fit this description, like the examples below. I paired mine with printed skinny pants to achieve a similar feel to the jumpsuit in my inspiration photo. I love this look and plan to wear it, my only concern is the fit of the pants in the waistband, which has to be perfect when your crop top showcases that part of your outfit. These pants tend to stretch as I'm wearing them throughout the day, and the waistband is already gaping slightly (like a lot of ladies, pants tend to fit me tighter in the hips, and looser around the waist). In this case, a longer white top like #1 below might work better. Some food for (shopping) thought!
