Is this season's Bachelor fashion the worst yet?

First impressions count on The Bachelor.

But during astrophysicist Matthew Agnew's season debut on Wednesday, the caliber of red carpet fashion appeared to be lacking in comparison to previous seasons.

From snakeskin, cut-outs, sheer gowns, wardrobe malfunctions and a WEDDING DRESS, there were several frock horrors from night one.

Frock horrors! From snakeskin, cut-outs, sheer gowns, nip slips and a WEDDING DRESS (ABOVE - Rachael Arahill)... is this season's Bachelor fashion the worst yet?

In an Australian first, personal trainer Rachael Arahill shocked Bachelor viewers, and Matt, by turning up in a wedding gown, complete with veil, train and a bouquet.

Wearing a bridal design by Judy Copley Couture, the 23-year-old was flanked by a 'bridesmaid' as she walked into the Bachelor mansion.

'I feel this is moving pretty quick,' Matt said in shock as they met for the first time, as Rachael described herself as a 'hot young bride'.

Oops! Model Vakoo Kauapirua at one point suffered a VERY awkward wardrobe malfunction as she exposed her bra tape in front of her rivals and Matt

During the cocktail party, contestant Vakoo Kauapirura, 23, demanded attention by strutting her stuff on a red carpet she had brought along from home.

Wearing a plunging pink dress, the model at one point suffered a VERY awkward wardrobe malfunction as she exposed her bra tape in front of her rivals and Matt.

She turned heads during the evening despite the flash of the tape, wearing a pink frock which featured beading on the bust, and a layered tulle skirt.

Another risky look was cafe manager Nichole Wood's nude-coloured dress, which featured cut-outs, a thigh split and a sheer beaded mullet skirt.

After first riding up on a motorbike to meet Matt, the 25-year-old slipped into the daring, embellished dress for the cocktail party and first rose ceremony.

Single mother Mary Viturino, 31, also opted for cut-outs and a plunging cut in a Judy Copley Couture gown.

However, the ladies weren't the only ones pushing fashion boundaries on the night.

Contestant Georgie Powell, 32, a cosmetic nurse from Queensland, wore a daring black frock that featured a sheer skirt.

The $579 dress by Lexi clothing left little the imagination, as it showcased her lithe frame in a tight bodysuit underneath.
