I usually go for brighter colours, but during winter dark blue is one of my favourite choices. Here I have tagged the green versions from the catalogue as I couldn't find the blue for some reason.
💙Saddle pad cotton jump: I really like this pad, as it dries easily after a wash. It fits well, has a good size, and looks nice but not too fancy :P I have used it a lot of times, still holds up very well.
💙Tiffany zip sweater: perfect for cold days, comfortable, and has a nice, soft feel to it. I should have gotten a M but instead ordered a L, didn't know PS fit true to size haha. So I'd recommend getting your usual size.
