I really struggle to know where to buy clothes. In my 20's I would have shopped mainly in newlook and H and M. I just ordered some t-shirts from H and M and the cotton is thin that they're unintentionally see-through.
I'm pear-shaped and wear petite trousers and dresses which makes things more difficult too. I find the likes of Zara fits a more willowy shape than mine, and again I've had problems with quality and stitching coming undone soon after purchase.
I want somewhere I can shop and know that the clothes are good quality and will fit and look well. I am a SAHM so I mainly just need casual wear.
