Vivien of Holloway is very niche. It looks great on some, but I have a sneaking suspicion those 40s and 50s styles would look hideous on very many. I'd love to be able to pull off a vintage-style dress, but at 5'11, its a no-go for me. I tried on a VOH dress once and it reached mid-thigh and made me look like a brothel maid.
Wrap dresses are mainly awful. I am tall and large of nork, and went through a phase of wearing them about 10 years ago, after the birth of my first DC, wen I'd lost my mojo and read stuff online about wrap dresses being the saviour of curvaceous women. I look back on old photos and think 'why on earth, woman?!'. They aged me by about 15 years and only accentuated the huge bazookas in a most unflattering way.
My niggles are:
Cos. Fucking Cos. 'Get yourself to Cos for workwear'. Why? Do I look like I work in a library in Scandinavia? Who looks good in Cos, really? Drab colours, straight up-and-down sack-like styles. Even the rail thin 22 yr old models on the website look depressed and shapeless.
Jeggings/Treggings. M&S/Next ones are apparently great. My eye.
Nobody looks good in weird legging/trouser hybrids. Get some slim, dark jeans instead.
