@CoastOfXmasPast Have you ever worn Ghost dresses? Some people say they're only for the tall, but a small slim friend of mine likes their dresses (sometimes needs to have them shortened, but not always).
@Mrsredlipstick (I think) made the point about plain dresses needing more structure to look modern. I think that's true - I would also say more detail. And that mixing not matching accessories looks more contemporary.
I don't think - from everything you've said so far - that you want to be super-fashionable as such - your look sounds like it's classic, polished & very smart. I feel for you though as a petite woman (both height & size-wise) - having looked at the ranges out there it's either on the formal/dowdy & very expensive side - or the tacky tatty polyester side!!
Coast is 95% wedding/evening attire - & 99% awful! Especially the fabrics ...
I did spot this though - more for this time of year (with a cardigan 😁!!) rather than summer though, & the colours are also more autumnal/wintery. It's not bad - but doesn't exactly say 2026, especially with the shoes she's wearing ... The chocolate & khaki are more "in", though khaki will probably stay around for longer as it's a bit of a modern classic neutral (if you suit it). Though to me the chocolate looks burgundy!
