I visit J.Crew stores, follow J.Crew news, articles and blogs on DAILY bases and noticed the latest trend for spring! Consider taking another look at "your boyfriend's chambray shirt", luckily for us J.Crew offers this top in a women's section: "This heirloom-worthy shirt has authentic details inspired by vintage workwear from the 1930s, and the Japanese selvedge cotton chambray is the best there is (we stonewash ours for that perfect worn-in look and feel). Boyfriend fit—casually chic with a longer shirttail hem and a slightly oversize fit (it's just like his, only you don't have to give it back)." J.Crew offers it for $98 item 15008 catalog/online only! Trust me I tried looking for it in stores, noone has it. The fit is roomy so size down and order accordingly.
Another item that sells well and is very popular is a schoolboy blazer in navy. It's fitted and tailored for a superb style. I think it goes well with a mini skirt, skinny black pants (think pixie, minnie styles) paired with a white oxford shirt, as well as any summer style cropped pants in light colors. It's offered at $198 item 17072.
