Underwear

Hi I'm a late 60s lady who loves strappy dresses and now we have the weather to wear them. I am looking for recommendations for a strapless supportive (38DD) bra that is easy to get on with arthritic fingers. I've seen lots of online adds for bras but don't know anyone to ask if they are as good as they make out. I currently wear an M&S multiway but have just purchased same one in same size and cannot even do it up!! Any help folks 😊
