I'm a mum of a 20 year old daughter and soon to be 19 year old boy, I know how much I had to pay out for their prom stuff.
I have more nieces than nephews and you should see what they are paying, the cost of prom nails is nothing but something every girl wants.
They want the dress, the shoes, the bag, the tan, the makeup and the nails, nails norm either French or full on bling matching colour to the dress.
I do prom deal shellac nails starting at £25 up to max top end £35 with nail art, rockstars, Swarovski crystals etc, this includes me going back for a soak off which i book at time of visit for max of 14 days later which they will have already booked in. If having toes done too then I'd add £15 for shellac or rockstar, I don't do Swarovski toes for prom deals. They get a pinkie oil free and if 2 girls same house I do a deduction of 10%. I don't charge for going back for the soak of unless they are having a new shellac, but most won't, to just a prom thing, but I already have booked it so can plan other things round it. Tho you can if need be sell the soak of kits so they can do it their selves.
Parents have never said a word about the price as its a one off and they like that to that its all booked for the removal.
I've had a few enquiries already from word of mouth and my leaflets being printed now, so going to be distributing that ASAP.
Average girl with dress, shoes, hair, makeup, tan, nails etc will spend 2/300 pounds around here, some do get cheaper dresses from abroad but they don't scrimp on the tan makeup and nails, so personally. Wuld not offer too much of a deal, do something that other places don't.
