I have a specific (boring!) style the suits me (I think?) of dresses or tops-and-skirts over thick black tights or leggings, worn with boots.
So far my 'capsule wardrobe' consists of:
3 x pairs of boots - slouchy tan leather ones, studded black high heeled ones and some Uggs. Only the black ones are new.
Lots of leggings (Top Shop extra long black ones are the best!), thick black tights and patterned black/charcoal grey tights (all from Primark for £2-ish. GSurprisingly good quality).
Various types of black or charcoal grey top - long, 3/4 or short sleeved. Mostly from Topshop or Dotty Ps.
Various dresses - mostly cheap & cheerful (Peacocks, Matalan, Primark and high street shops) fitted tops with flary skirts.
Lots of cheapo accessories - big, stretchy, wide belts a must. Love gun metal silver/grey or that kind of bronze 'old gold' jewellery. Also lots of colourful beads.
Various styles of black cardi - long sleeved Grandad oneas from Topshop are my favourite
2 parka jackets - an army green one (New Look) and a slightly shimmery black one (M&S last year)
