Can not wear a bra with this dress but you can use fashion tape.

Rented this before there were any reviews and was so glad I did! The fabric is absolutely wonderful, very high quality. The tie waist is very flattering. The dress is well-lined, so you don't need a bra (note: I'm a 34DD and pretty comfortable going braless). You will need to wear nude undies or a slip though, as darker color undies will show in the sunlight (luckily my partner caught that before we left!). Was the perfect outfit for a walking tour, the light fabric and floaty skirt kept me very cool.

Bust fit REALLY strange, gapped at the top but tight in the middle

…. And I have very large breasts. There was so much extra fabric and I had to pull on it all day long because the straps are not adjustable.

I ended up not wearing because it was gaping in the chest and the straps are not adjustable. It was almost comical how bad this fit. The skirt is also pretty sheer.
