Ever since there have been boyfriends and girlfriends, girlfriends have been wearing their boyfriend's clothing. It's comfortable, and can even be stylish, if done right. There are several takes on wearing boyfriend clothing, so you can find one that suits your taste.
One of the most popular ways of wearing boyfriend style clothing is to wear loose garments, but it's important that you don't look like you're swimming in them. You want to look like you're borrowing your boyfriend's t-shirt, not his circus tent. Additionally, while loose-fitting is good, you don't want to wear loose clothing from head to toe. The most effective way to use this look is by making it a study in contrasts. Wearing a baggy top will make legs look longer and leaner in comparison. A loose bottom will highlight your curves in a fitted top.
Boyfriend style jeans have also become quite popular. Still designed with a woman's curves in mind, they are looser and available in an assortment of styles and washes. To ensure the best look when buying this type of jean, make sure the pair you purchase has a straight leg. Boot cut and flared styles don't really channel the boyfriend look, and completely defeats the purpose of not just buying a pair of regular women's jeans in these cuts. Ripped and worn looking boyfriend jeans are the most popular, but you can buy them without the weathering.
Much like you'll want to avoid a baggy look from head to toe, the best way to wear boyfriend jeans is to contrast them with feminine garments. Wearing the jeans with girly top and heels looks chic, but is still comfortable. Many celebrities wear them with high heels and fitted tops. You can also add more masculine notes to your outfit, pairing boyfriend jeans with a man's vest over a fitted tank top will emphasize curves, while still following the trend.
The boyfriend look is a great way to dress casually, but still look stylish.
