I purchased two Jean Boleros from Ponyboy. I use the black one nearly every work day. I have my uniform and it just covers my arms to help keep the chill off them. It is very dressy, I machine wash in a bra bag and it comes out looking like brand new every time, so it is a quality item.
I also use them both when going out dancing. I do not like hot dresses to dance in the the little bolero helps with the warmth until I get up on the dance floor.
go buy yourself some and listen to Serene on the sizes for yourself, as she is a whizz at it. I got mine at least two sizes smaller.
