I bought this dress for my summer wedding several months before the date. I ended up falling in love with another dress a couple months after ordering it, but it was too late to return the dress to BHLDN. It's never been worn other than just being tried on.
I got the dress from the BHLDN website - it is actually listed in the bridesmaid section because it comes in a lot of different colors. The dress has tulle panels in front and back that can be used to style the top of the dress multiple ways from strapless to halter to off-the-shoulder. You can look on the BHLDN site to see the various ways it can be styled. It fits true to size with maybe a little extra room in the bust. The construction of the top/bodice area is very solid and not flimsy at all, therefore you would not have to wear a bra if you didn't want to. It has a simple concealed zipper in the back and an additional tulle sash that comes with the dress.
The feel of the tulle is soft and airy, with a more form-fitting lining underneath. The bodice is lightly pleated to give a little extra detail. I was going to wear a beaded belt similar to the one pictured in the BHLDN images to give it a little something, but it also looks great without a belt or with the tulle sash tied under the bodice. I would say it is a light off-white color, more on the white side than the ivory or champagne side.
I've included a photo from the listing on the BHLDN website where I bought it as well as photos of the actual dress. It is a gorgeous and simple gown that gives a much more sophisticated and beautiful look than it's inexpensive price tag would suggest!
NOTE: Beaded belt shown in first picture not included - that is an accessory on the BHLDN website that they used to style the dress that you can purchase from them separately or add your own belt/sash.
