When I was unable to find a dress that was similar, the reader suggested a tank/skirt might be easier to find, so I began my search. I found this tiered tank from Madewell (which varies in that it has tiers and the P. Lim version does not) which had a similar eyelet detailing. It retails for $38 and you can click here to purchase.
The skirt I found doesn't have any eyelet trim, but I think it would work well to give you an inspired by look. It retails for $69.50 and you can click on the photo to purchase.
