Wear Comfortable Clothes While Practicing Yoga

Comfortable and functional Yoga clothing helps participants practice Asanas (yoga postures and poses) more effectively. There is no strict uniform for Yoga classes (though some studios may encourage certain apparel), so participants are generally free to wear whatever makes them most comfortable.

Yoga Tops For Ease of Movement
Yoga tops are generally made from light materials like cotton or Lycra, and should never restrict movement. Students may consider wearing one of the following options to Yoga class.

Lightweight T-Shirts: A thin, lightweight tee offers a good deal of coverage while allowing a full range of movement. Light, organic fibers let air circulate through to avoid overheating.
Tank Tops: A tank top is a popular alternative to a t-shirt. It exposes more skin and will tend to be more formfitting, which some people may prefer for working out. Since there are no sleeves to worry about, a tank top does not restrict movement at all. It also allows the Yoga instructor to clearly see the position of the body and make adjustments if necessary.
Sports Bras: For a woman who is confident with her body, a sports bra may be ideal. Forms of Yoga like Bikram and Hot Yoga, which encourage heavy sweating, are most comfortably performed in minimal clothing.
Yoga Bottoms for Maximum Comfort
Pants used for Yoga tend to be very multipurpose – they can be worn to all different types of exercise classes and they also make comfy lounge wear for lazy days at home.

Yoga Pants: There are pants which are specifically made for Yoga (thus the name “Yoga pants”). They are loose, lightweight, and usually cropped around the knee.
Leggings: Leggings are formfitting and occasionally too tight, but sufficiently stretchy leggings can make a good choice for Yoga clothing.
Shorts: Loose, light running shorts or shorts made of a stretchy material like Lycra are another good choice for Yoga students. Jean shorts are a definite no, however, as they are bulkier and restrict movement too heavily.
Unitards Are Popular in Yoga Classes
Some people may prefer to wear a unitard to Yoga class, which looks similar to a one-piece swimsuit. This allows the ultimate in body positioning without hindering movement or flexibility in the legs or arms.

Socks, Shoes and Bare Foot Choices for Yoga Footwear
Some Yoga studios require bare feet, but others will allow students to optionally wear special Yoga socks or shoes. A pair of lightweight yoga “slipper” shoes or “sticky” grip style socks specifically made for Yoga can help prevent slipping and provide extra padding for sensitive feet. It can also reduce concerns about hygiene for those not comfortable practicing in bare feet. Source
