I tried it on once, but the size didn't fit, so I took it off immediately. I haven't used it outside, it's like new/unused. I'm selling it because the size doesn't fit my dog (5.7kg). Similar items are being sold a lot, so I'll omit the photos. I bought it here: https://item.rakuten.co.jp/ziimo-co/10000754/?variantId=r-sku00000004 Item Details: ◆ Size: S ◆ Color: White ◆ Material: Polyester, etc. This is a vest with a built-in harness. It's fleece-lined and warm. The zipper on the back made it easy to put on and take off my dog. The pockets are real and cute. The photos were taken with size S. ------------------------------------------------ ▼ Sizes: Length / Chest / Neck 【 XS 】: 22cm / 33cm / 21cm 【 S 】: 25cm / 37cm / 24cm 【 M 】: 30cm / 42cm / 30cm 【 L 】: 35cm / 49cm / 35cm 【 XL 】: 39cm / 52cm / 38cm -----------------------------------------------
