Lands End, the only place I can get tall women's tops. Their USA parent site sells even more. I'm about to throw out a top I bought from them, wore and wore, that's 15 years old, always goes through a tumble dryer too! My top tip would be to sign up for their emails, as they always have silly offers, sometimes up to 70% off, over 40% off everything. Look at their catalogue or website, put the items you like in your basket, but leave them there until there is an offer. I have an idea that if you don't buy things in your basket immediately you are more likely to get a special offer. Until recently I'd give them 100% but some of the tops I've just received are lighter than their usual fabric. Returns are easy though. I also love their trainers, extra wide available.
