This is an awesome floral set from the early 90s or late 80s!
From the brand Deb.

The only flaw I found is an odd stain in the front left chest area. I've pictured it here. Its actually covered by the lapel when worn.

The jacket is tagged a large and fits true to size but the skirt is an 11/12 which in vintage sizing equates to a modern day 6 and fits like a 6.

The best thing about sets is that you're getting two pieces that can be worn together but also as separates. I've shown the skirt on it's own here as well as the jacket with jeans.

Skirt waist laid flat 13.5 inches
Total length 29 inches

Jacket length 26.5 inches.

Jacket is definitely quite oversized in comparison to the skirt and fits more like a large.

This item is sold from a vintage seller in Central Wisconsin.
