This is a Calvin Klein set purchased from the official Amazon shop. The bra has been washed, but the shorts are new and unused. I realized I bought the wrong size (L) because it's too big, so I hope someone who wants it can use it! I once bought Calvin Klein from Mercari because it was cheap, but the material and logo looked completely different and cheap... If you're buying, definitely go for the authentic product! For reference, here's the link where I actually bought it (it's already sold out): https://amzn.to/3IAUZxp Original price: ¥21,285 【 CALVIN KLEIN MODERN COTTON - Bra & Shorts Set 】 ■Highlights ・Comfortable item with soft, skin-friendly cotton fabric and moderate stretch ・Breathable cotton blend material that can also be used as a sports bra …………………… Underwire: × …………………… ■Material Soft, skin-friendly cotton fabric with moderate stretch for a comfortable fit. ■Size Guide XS: A65 B65 S: A70 A75 B70 M: A80 B75 C70 L: B80 C75 D70
