Hey!
Ooh, sounds like we're quite similar style wise! You can definitely do 'grown up goth'. I've attached some images along with some ideas for wearing DMs and dresses. Tea dresses look amazing with DMs and can be nipped in at the waist. Don't have to be as short as ones in the pictures but just as an idea. And can add a black polo neck under for winter.
If you look at your veins' on your wrists. If they look really blue then you're cool toned, if they look green you're warm toned (incidentally I'm very pale but am actually olive toned due to being from southern Europe heritage which is a whole other ball ache
). Your colouring sounds amazing
I think the skinny jeans in the basket would look great with DMs. Try the bootlegs and see what you think but I find them hard to style with the right shoe! The green top has a nice tie in at the waist so worth trying but I personally would find the sleeves hit me at the wrong point but they may work on you so worth a try (I'm really quite busty -39-28-40 and 34F).
If you search for giuliva heritage x h&m on h&m (a lot has sold out)but you can just see the silhouette that would look great on an hour glass even if the colours/ styling isn't what you'd plump for. Kind of 'got my life together' winter chic.
Primark do some really nice polo necks and jumpers that are not too bulky in a nice stretchy wooly fabric that look cool goth'd up with skinny jeans and boots.
If you do want to avoid anything clingy on the stomach area, I find a slightly oversized t shirt/jumper in a French tuck (thank god I got that the right way round
) draws attention to your waist but allows you some 'breathing' room.
A cool way to get a good silhouette is to dress in one colour. We tend to do it with black but head to toe in any colour can look really cool. So, once you know if you're cool or warm toned you could pick a aubergine shirt/top and trouser combination of emerald green. Just looks really chic. I love black and find adding texture stops it looking like you're trying to be a mime. So, a denim jean and woolen top with a leather jacket and docs looks cool.without looking flat.
And finally, a trench coat is always a nice addition to an hourglasses winter wardrobe. It's important the belt hits you on the waist. I'm 5ft10 so find ASOS tall good for them but have to say Primark has had some ace ones in recent years so worth waiting until a few weeks into September and seeing what they have (if you're ok with that at the moment).
Exciting stuff!
