My in-laws run a fancy-schmancy exclusive hotel in a wealthy part of Switzerland. Most guests there will be decked out in expensive designer clothes, furs in the winter, etc.
I will feel a little out-of-place when we visit as my wardrobe mostly consists of charity shop bought clothes, alongside Primark, New Look and supermarket brands. Not only that but most of it doesn't fit me now I'm breastfeeding my new baby anyway. So I need to update my wardrobe.
I've still been shopping as if I'm a broke student despite being on a fairly good income now. Any suggestions of where to buy a few key pieces of good quality, classy, more expensive-looking clothing for a trip like this without spending more than £100 on a single item such as a dress? I'm happy to eBay it, I just don't know what brands to look for!
(If it helps, I'm mid-20s, probably dress more like I'm mid 30s... I like simple, smart, classic styles. I tend towards dark colours like navy, burgundy, black.)
