I used to have a pair of these as a teenager. Would they look alright as a 34 year old or would they shout mid like crisis? I fancy getting a cherry pair to wear this winter with skirts, dresses, and jeans in a casual way.
I've recently bought a very nice pair of DocMartin boots, and I'm 34! They are great, very lightweight and comfortable. I still have a pair of purple DMs, nearly 20 years old, bought with my first saturday job money, and still uncomfortable but I love them.
I think DMs will be fine, I still have a pair of steel toecap 10-holers and some knee high boots which are a pita to get on and off. And I'm marginally older than you.
However, I'd avoid cherry colour - they have a certain 1990s-ness to them so seem dated, particularly if you remember them the first time round. To me, cherry DMs shout indie/crusty, Levellers, tie-dye maxi skirt, frayed jumper, patchouli oil, Charlatans, needledread hair iyswim.
DMs do some lovely other colours if black is too boring - they used to do a gorgeous dark green and a really vivid ultramarine blue.
I bought my latest pair of cherry red, 8 holes last year. For some reason when I'm prpegnant DMs don't fit me so as sson as i was a year beyond pregnancy I got them. I'm 30 now, don't think the look 'midlife-crisis-'esque. If they suit you as a person they will look good.
