1970s Benny Ong for Mushroom Boutique Red Halter Neck Dress


This crimson red maxi dress is an early design by Singaporean fashion designer, Benny Ong, for London label Perlei’s highly collectable 1970s line Mushroom. Ong’s private clients for his eponymous label have included Princess Diana, the Duchess of Kent and Queen Noor of Jordan. This event-worthy dress is tailored to cascade in ruffled, red manmade chiffon layers to the floor. The top is cut in a halter-style which is adorned with ruffles the whole way around the body. The body of the dress is double-layered with the long bottom layer and shorter top layer swirling around the wearer and echoing their movement - a fantastic dress to dance in that hints at traditional flamenco styles. The dress fastens at the back with a tonal red zip and hook-and-eye clasp.

The original label has a 'trippy mushroom' design which has been remembered by fashion collectors over the years. There is no composition or size label so please check our measurements for fit; we estimate this dress will best suit sizes between UK 8-12 or US 4-8 with a smaller bust. There is no stretch to the fabric. In excellent vintage condition with no flaws or marks noted. Our model is a UK 6-8 and 5ft 4in (163cm) and this dress fit her well. We haven't, but tape could be applied to the bust to provide more secure coverage.

Will you set anything aside for me before I come?

We are happy to find anything you may be interested in from our website - please let us know a week in advance. 

We also have an extensive offline collection. If you let us know your size, style, favourite colour to wear and perhaps your budget, we can browse through our archive in advance of your appointment. 

Do I need to bring anything with me?

Clients may wish to bring modern shapewear when trying on garments from certain eras, especially the 1950s. Vintage clothing was often worn with undergarments that shaped the waist and as such is tailored for them.

We have a huge variety of slip dresses and petticoats to complete your look; many of which are also for sale.

You may also wish to bring your favourite footwear. We often find a classic pair of nude shoes work well when trying on, or a pair in gold or silver.

Do you have a price range?

Many of our lower-priced pieces (under £150) are not available to buy online. Our prices range from £80 - £600 for separates. Dresses start at around £150 and go up to £2,500 for the very best antique pieces and designer vintage. Our bridalwear ranges from £300 - £3,000.
