I find 'butterfly houses' to be magical and your blouse sounds magical as well!

This sounds off-topic but isn't, really...since I do not know what gardening zone you are in this might seem an odd question but do you ever plant either Lantana or Heliotrope (proper name Heliotropium)? The reason I ask...

The porch on the front of my home (having been built in the 60's) has built in (with slate/rock) planters that rest just above a flower bed that line the porch. I plant several (and I do mean several) lantana plants in the bed and planters - and then plant heliotrope also in the planters but add pots to sit on the porch. My porch is covered. By May - my porch has become a "butterfly house" and it is magical. They will land on me, my book, the chair...and flutter around the flowers all summer long.

The moral...if you are in the appropriate planting zone - get you some lantana and heliotrope - it works!!!

Back to your butterfly blouse...it sounds comfy and the perfect outdoor attire.
