Unique linen summer dress!

I bought this dress in Spain and have never seen anything like it in the States! I’ve only worn it a couple of times. It’s tan linen with red/navy lines. Hits above the knee. I’m some pictures it looks strapless, but it does have tan spaghetti straps. Zip closure on the side. It’s a size 38 Euro which is generally a 4-6 in US sizing.
