This is a sports bra with a back strap purchased at Lululemon Ginza Six. It's made of stretchy fabric for a comfortable fit. Size 6 White I'm selling it because the size was too small for me. It's almost new, only tried on. I will also include the Lululemon bag it came with♡ Perfect for yoga, training, walking, running, the gym, etc.♡ Because of the back strap design, it can be worn not only for sports but also as everyday wear, especially in the summer for light clothing. This is a used but beautiful item, so please understand that it is a USED item before purchasing. Anonymous shipping. I am committed to a courteous transaction until the end♡ Thank you very much.
