My first real triumphant eBay score came in the form of this puff sleeved vintage bolero. Oh how I love it's huge, exaggerated, scrunchy sounding shoulders. Whilst it cannot fit under a jacket, I make do by taking it in a bag and wearing it once I reach my destination. It looks best when worn with other items which similarly play with shape or volume in some form.
It feels like I'm wearing giant black flowers on my shoulders. Twas money well spent for that alone methinks!
