Sylphide: Satin Corset 18"

I have another 18" satin corset (from TGC), which is my newest one. Below you can see some photos of it. The lower part is not very tight, but the ribcage is compressed considerably. The effect is especially significant with the lower ribs. Therefore I need a longer time (1-2 days) to get used to wearing this corset and feel comfortable in it.
