Trinny Woodall has had a hilarious blunder on Instagram this week.

The British fashion adviser, designer, television presenter and author is best known for her regular appearances on This Morning.

She is best friends with fellow fashion expert Susannah Constantine, and has written a number of books and presented various TV shows as the duo ‘Trinny and Susannah’.

This week, Trinny decided to show off her latest fashion finds on Instagram, where she has 984,000 followers, and made an embarrassing blunder she’ll never forget.

Trinny Woodall flashes on Instagram Live

Trinny went Live on Instagram on Wednesday (September 22nd) to model some new clothes.

She tried on a green floral co-ord set from Zara, but decided she didn’t like it very much and wanted to return it.

The 57-year-old began unbuttoning the top before pulling it over her head, which caused her bra to ping undone.

She then quickly rushed off-screen whilst saying: “What a great bra, it just came off. I was just about to flash you.”

However, what she didn’t realise is that she had very visibly flashed her whole breasts and nipples to her followers.

Trinny has now deleted the video from her account, but you can watch the blunder on Twitter here.

Thankfully, the nip-slip didn’t seem to bother Trinny much at all.

She commented on her own post “it’s only a nipple”, showing that she really didn’t care about the blunder.

As a fashion expert who is always trying on clothes, it’s probably not the first time it’s happened to her, nor will it be the last.

She has just launched new Trinny London products

Less than 24 hours before the Instagram flash, Trinny celebrated the launch of her new Trinny London collection.

The fashion expert has her own premium beauty brand and was in London promoting it on Tuesday.

She wore a bright yellow suit and rose a matching yellow motorbike complete with the Trinny London logo.

Trinny paired the look with round sunglasses, silver heels, silver Prada bag and a white t-shirt with minimal jewellery.
