Beyond Yoga
Why? I stumbled upon Beyond Yoga at a really posh Yoga Studio and immediately fell in love with the fabrics. The Space Dye collection is beyond soft, perfectly compressive and high quality. I have had 6 pair of leggings and shorts from Beyond Yoga for years now and they still look and feel brand new, while other brands have pilled and worn out. I even like their cropped tanks and bras, which is rare for me as I am so particular on this type of fit. I also love that the brand is size inclusive and offers petite to 4XL in most styles.
What? The leggings and biker shorts are a must have for me. For leggings, I always go for high waisted and long, with or without pockets. For the bikers, I like the longest option, with or without pockets. I do like to buy corresponding bras or cropped tanks to match my shorts and leggings since matching is really a thing these days. I want to try their looser style tees and tanks as well because the fit is super body complimentary. The onesies are on my list to try as well with a few of the dresses and joggers. I would stay away from the sweatshirts and jackets as the fit looks awkward, and same for the dresses.
Where? BeyondYoga.com is a great options for the full range. Carbon 38, FWRD and Nordstrom all carry the line as well with color and print exclusives. These stores are a great resource if BY is sold out of a certain color or style in your size.
