I don’t know if Aerie calls this a bra or a bralette but I will go with bralette. The cups are a simple triangle with lace trim and elastic along the two upper edges. The lower edge is lightly gathered along a very short and shallow underwire. The adjustable stretch straps are doubled in back and trimmed with lace. Fastens in back with two hooks. This bra may be a second, since the name is marked out on the label. This style does not appear on the Aerie website.
