(Image credit: Athleta) Athleta is one of my favorite places to shop for yoga apparel, and right now, the store is practically giving things away. A lot of classic pieces are already 30% to 50% off, and from now through May 17 at 11:59 p.m. PT, Athleta’s doling out an extra 20% discount at checkout on a lot of sale items. This incredible sale is making some items over 75% off their original price, including these Interval Stash High Rise 7/8 Leggings slashed from $109 to just $23 or (my favorite deal from this entire sale) this BodyMove Plunge Bralette knocked from $39 to only $9 . Other items are just good deals on their own, but don’t have that extra 20% off sweetener at checkout, so double check before you pay. Scroll on to see more of the deals that caught my eye while shopping, or head over to the site to shop Athleta’s entire sale from $4 for yourself.
