Anyone willing to give me some guidance?

[thankfulforeverything]

I have never sold clothing before but I have two very limited edition preloved Glastonbury barbours. They are customised by Barbour with inserts featuring the bands that performed at Glastonbury and they have matching bucket hats.
One is mine one is my husband's they were gifts from some Australian friends who were staying with us and they went to Glastonbury and bought them there's Thankyou gifts for us.
I have no interest in wearing them but imagine they cost quite a bit.
How do you value stuff? Where would you try to sell it?
I looked on eBay but couldn't see any examples.

The best site would be Vinted, I think. However, you won't get anywhere near the purchase price for them. The Barbour website does feature the Glastonbury range, look here :

Would have been very expensive new.

I'd do Depop or Vinted.
Depop you'd usually get a higher price and the right type of buyer. Especially with a description stating limited edition deadstock etc
Search for them online and see how much they were new and then decide how much you'd be comfortable with taking off. Otherwise I would just wear them as a dog walking or hiking jacket

Are they these?

They’re likely to be worth a small fortune - I’d eBay them as you’re likely to get what they’re worth. Before doing that you could contact Barbour to ask what they think about value or continue googling until you find very similar so you can accurately gauge the value.

I wouldn't sell anything worth a lot of money on Vinted

Yes that's them they have special badges and materials . Plus the hats.
TBH they are a bit too grungy for me
I'll look at Depop which I'd never heard of before!!

I agree. Vinted is full of scammers, especially when it comes to higher priced items. eBay offers far better protections for sellers and has actual customer service if you ever have an issue. You could even try an auction house if there's one that sells that kind of thing.

Don't sell on vinted, and don't post anything to the buyer until you have received the full payment and then leave it a couple of days in case they try to claw it back.

Wow !! Thankyou .

Agree, avoid Vinted for anything valuable! EBay would be better although may take longer to sell. There are also several designer buying/selling groups on Facebook that may be interested if you’re on FB.

You want eBay, VINTED is for cheap stuff. I am an eBay seller, make sure you research the sold and completed price, not the ones for sale. Anyone can advertise anything at whatever price they want, that one linked above is a crazy price and isn't sold. A Barbour will be about £40-£70 sold depending on condition and the rating of the person selling it. I don't know about yours but you can Google image search it to see what the right price is.

Thankyou so much fir all your replies.
Maybe I'll just think about it a bit more

Just adding, don’t sell expensive stuff on Vinted. You will likely be ripped off.
