As a 40DDD gal who's struggled with bras my whole life, this Olga bra is a GAME CHANGER. No more spillage, no digging straps, and zero uniboob - which is basically a miracle for wireless bras.
The XXL fits me perfectly (finally a brand that understands sizing!). The sewn-in cups give great modesty without bulk, and the stretchy sides don't feel like they're trying to strangle me by lunchtime. Major plus: works under low-cut tops better than any camisole I've tried.
After years of sports bras that smush or 't-shirt' bras that lie about their coverage, this is the first bra where I've actually felt supported AND comfortable all day. The microfiber fabric breathes way better than I expected too.
Pro tip: If you're between sizes like some reviewers mentioned, consider getting an extender rather than sizing up - the cup proportions stay perfect that way. Seriously considering buying three more now that I've found my holy grail bra!
