The Kusidelko and Amorek are simply 3DM in sister sizes. I fit UK28F often, but find 30E usually more comfortable (27 inch UB). I find EM 70DD and 65E both comfortable and well-fitting. I suspect I may prefer the 70 band in Ewa after all day wear, but so far both seem OK.
I find all of the cups on these to be lower than what I am used to. I feel a bit "exposed", but I think I will get used to it. It isn't bothersome, but noticeably different. I read about people ordering reduced cups on EM and I really can't imagine that, these are low cups already IMO.
I also ordered matching thong panty. I am not usually a girly-girl, and usually don't like heart decor, but I have to admit this Amorek set is adorable.
