These adorable Enza Costa peplum pants retail for $425 at Shopbop, and sold out in most sizes.
I found (and ordered) these incredibly similar Mango pants which retail for a lower $79.99 which you can purchase HERE and available in all sizes.
Awhile ago I saw an influencer wearing this By Malene Birger Trinola top with Chan Luu taffeta pants and it was SOOOO good. Sadly, this top is mostly sold out but if it's in your budget it's $475 (but on sale for $332.50 in limited sizes HERE).
This striped dress from Chanel with the fringe at the hem retails for $5950 on the Chanel website as part of their Cruise line.
Not the exact same color wise, but this will definitely give you the Chanel look on a budget. This version retails for $54.99 and you can click HERE to check it out.
This Staud Calluna Organza maxi dress is gorgeous and retails for $495 at Saks.
If you like the style of the Staud dress, check out this version from Few Moda. If you're a member (I believe it's $39 for a 3 month membership, so worth it for the savings honestly) it's $98 or you can purchase it at a non member price of $245. Still a deal, honestly.
