Yes it is May. Yes I live in Florida. But it still is a bit chilly in the AM! Especially when you're at a show and you are up long before the sun rises. I think vests are so great for the barn because they are super easy to take off, you have more pockets to store things in, and you still have freedom of movement with your arms for riding.
I can't tell you how many compliments I get on this vest. It's totally a game changer and it shows because it is almost always out of stock. I managed to get this one while I was working for JCrew so I got inside hook up! But... JCrew Factory has them on sale right now for under $50!! I just love the pattern because it goes with everything. It looks super classy paired with all black, but I've totally worn it with jeans, tan, bright colors, etc. The gold accents give it that high-quality, equestrian look I love. I ended up getting mine in an XS because that is all they had left. I was a little nervous because I am usually a Small or even a Medium for outerwear, but the XS is the perfect fit. So I would say if you have a choice, don't be afraid to size down.
All in all, I was so happy with this purchase and I think it is one of those classic pieces that will always be in the forefront of my wardrobe.
