Spring wedding dress guest - where to look?

[AliasGrape]

My niece is getting married in the Spring and I want to look for a lovely dress for it. Dress code/ theme is 'spring garden party'.

I've lost a lot of weight over the last couple of years, so I'm thinking I might be able to try some different styles now and want to look outside my usual places where I end up in the usual v-neck/ wrap type midi dress (can't deny they look best on me though!).

Budget isn't huge - I'd go up to £120 ish for a dress, then obviously would need accessories etc. If there's a more spendy brand you'd recommend please do say though and I can look on Vinted etc.

More looking for overall ideas/ places to look/ brands to search, but if anyone has specific recommendations for dresses/ outfits they've seen I'll share that I'm mid-40s, was 'analysed' as a muted Autumn colours (key points being no black and muted colours work best for me), and hourglass shape, size 12/14, something of a belly still and big boobs. I'm 5'6.

Thank you in advance!

Sosander and Abercrombie & Fitch have some nice midi dresses. I have similar body shape to you and find that the usual brands (Reiss, Jigsaw, Whistles) do not offer styles that suit me.

A&F dresses are well tailored, and I mentioned Sosander because they had some nice ones in that spring garden style last year. Those brands would probably come in a little under budget for you and will leave money for the extras.
If possible, I’d scrimp on your bag and shoes (Primark/Vinted) and invest in some decent underwear so that on the day you feel really good!

this green dress is within the autumn palette But they do have lots of floral printed dresses which may fit the garden theme more!

That green is lovely thank you!

Not a brand I’d ever have thought to look at so I’ll have a browse now.

Nor would I have ever looked before but I found a dress (sadly not on there anymore as I was going to recommend it) and it fit like a glove so I was impressed!
