'Sexy' mother-of-the-bride dress shocks Twitter

One of the biggest fashion mistakes a guest can make at a wedding is trying to upstage the bride.

Anything that will take the attention away from a woman on the most momentous day of her life is a big no-no.

So a dress marketed as a "mother-of-the-bride outfit" probably shouldn't be a black plunging, low back number with a boosted bustier and sheer lace panels, right?

The sexy dress in question was made by Bulgarian designer Tonena, and is causing a major stir on social media, with people in awe of the bold fashion statement.

The dress also features removable sleeves and a back that could be left open or closed, from those "aiming for a more conservative look".

However Twitter commentators appeared to be loving the less-than-wedding-appropriate dress, with some comparing it to villainous characters Maleficent, Moira Rose from Schitt's Creek and Cruella de Vil.

This dress alone is a 3-season drama on Netflix. I’d watch.

One woman who wasn't keen on the dress suggested she might add it to her "no-no page" for her wedding, just in case anyone was inspired by the saucy number.

Another wrote she was going to get the dress and wear it to: "chaperone my sons to their first school mixer in a few years".

If you too are feeling inspired, the floor-length mermaid dress with cost you $3481, and for that price it better be serving up some serious vibes.
