Alter as you go
I regularly say to clients ALTERATIONS will change your wardrobe… I will often suggest to get a sleeve length shortened or a length of a hem altered so it’s modern and flattering (where tops finish can be crucial to something working well or not working at all) as quite often the piece in question is great (almost) and made from beautiful fabric.
I have recently altered three of my dresses as I had stopped wearing them. It has made them look current again and not nearly as dated or out of tune as they looked before. Find a good alterations person, preferably someone with small overheads so you are paying for the workmanship and skill and deal with them directly - just another thinklikevink tip.
