RetroFairy were so quick to communicate and easy to order from. Very polite and helpful.
My waist is 67cm and bust is 85cm. I got size M. It fits really well just by itself. The size I got was a bit tight for layering, so keep that in mind when purchasing, definitely size up if you want to layer it on top of other clothing. The design of the fabric is beautiful and as depicted in the photographs. I got what i expected to purchase! A beautiful corset.
Why it isn't 5 stars is because the seams are a bit messy, with unfinished threads and it also came with one of the eyelets dislodged. It's nothing hugely negative in the quality, mostly just nitpicks. They are easy to fix.
