I did go to Sogo today and found a suit. It was on the floor with the sports wear, but you have to kind of hunt around for it, I felt like. I am not really a huge fan of SOGO (intimidating!!) and I had my two kids with me, so I didn't get to look around as much as I had hoped. But like I said, I did find something, and it was on sale for $269. Still a little more than I wanted to pay, but it's a good brand and I think it will last me awhile. Looked like they were having a lot of sales, if anyone else is looking for a swimsuit.
By the way, they had up to HK size 40
