Purchase all 4 or just 2! Since losing weight these are too big in the chest for me now and I prefer to wear a less structured sports bra. All have been worn to workout at least 5x or more The shefit logo on the back does to tend to peel off in the wash over time. Sizing has also mostly rubbed off but the orange & black bras in one photo are a size “Luxe” the other black and pink bra are a “1Luxe”. If you’re unfamiliar with their sizing PLEASE check out their website. Bundle is $40 for all 4 or $20 for 2.
