This is a denim jacket from Polo Jeans by Ralph Lauren. The size is 2T, but my son wore it until he was 3 years old. He can still wear it now that he's 4, but it's still in good condition, so I'd love for someone to wear it a lot! It's a denim jacket, but it's not too hot, and the denim is soft, so you can wear anything underneath, like a sweatshirt, sweater, or T-shirt. It doesn't feel bulky, so it seems easy to move around in. The hardware is also easy to remove. Please only purchase if you understand that this is a used item (⁠.⁠ ⁠❛⁠ ⁠ᴗ⁠ ⁠❛⁠.⁠)
