Affordable outfit ideas for an upmarket Mediterranean beach club day

[ChampagneCharlotteLemonadeBudget]

So I'm going to a very very upmarket beach club in the med for the day in June, and seriously need an outfit that's going to look the part but I'm also on a very, very tight budget. My experience of beach clubs is more like O Beach Ibiza from my younger days, and this is about as polar opposite as you can get. It's in a very glamorous resort that's full of yachts and 'beautiful people' (light-hearted but I'm talking minor European royalty rather than Instagram types)

I'm 39, 5'1" with dark blonde hair, blue eyes and a tan (well by then I will). My figure has always been an hourglass and I've recently gone up from a 6 to an 8 after a hysterectomy last year - not feeling v confident currently about my stomach, thighs or hips, but am trying to work on that as much as I can between now and the trip!

Budget really is as little as possible - happy for suggestions from Shein, etc. (Please no comments - I'm asking what I CAN wear). I don't need a bag or shoes but need something to swim in, a cover up that I can also eat lunch in and potentially even dinner, and maybe some jewellery. Bonus points for any sunglasses too, although I do have a couple of real designer pairs I can use.

Oh and just to pre-empt any comments around going there but being on a budget - I'm not having to pay a penny for the actual day itself, and the holiday etc is already paid for last year

Stick with a neutral - black or white or beige, whatever suits you. I'd go for an outfit like this

Linen-blend straight skirt - Women | MANGO United Kingdom

Or the skirt with a loose linen oversized shirt in either black or white.

A bikini or swimsuit should be easy enough to come by.

Appreciate you have a small budget, but I would try and find something basic in a decent fabric like linen or cotton and wear that with your designer sunglasses.

If you're set on Shein, google maxi beach co-ord and there are lots of Shein options.

Oh and I meant to add as well that the boob area isn't an issue as they are fake
