This is a convenient outerwear that can regulate your temperature, whether you are worried about the sunlight during your commute or feeling cold from the air conditioning on the train or indoors. The moderately sheer knit fabric gives a refreshing feeling, and the light feel is convenient for the sweaty season. It can be folded up small and put in your bag, so it is convenient to carry without taking up much space. It is a buttonless topper style that you can easily put on, looks like a bolero, and has a longer length at the back for peace of mind.
