Argyle/Argyll tweed Jacket and Waistcoat Advice

[TheBlueRaja]

Hi Everyone,
I found this forum whilst looking for a new Jacket and Waistcoat to replace my current PC Jacket and Waistcoat that's seen better days and was hoping you could steer me in the right direction.

I think i've settled on an Argyll Jacket and Waistcoat but had a couple of questions regarding exactly what to go for.

This will mostly be used for Weddings, probably my own too, and evening events etc, so I really want to get this right.

Firstly, I like the look of the tweet Jackets / Waistcoats supplied by Scotweb and the like but I wondered also, if being tweed, they might be quite hot to wear.

I've been to many events where i've been roasting in my PC which is only an ex rental, standard wool one and wondered if tweed would be hotter than my PC or say an Argyll wool one that isn't tweed.

Secondly, I'm finding it difficult to work out which ones are good quality and which ones are of lower quality other than blindly thinking price is king and the oz of the jacket.

Generally the price seems to be around the 200 - 300 mark for a Jacket and Waistcoat combined (tweed, charcoal ARR001, 46 Regular).

However depending on where you look, I'm seeing 15oz tweed from here for £180 (light charcoal only).

17 oz Arrochar fabric Tweed in a more preferred colour (ARR001) for £195 here.

Or the most expensive option, the Tweed Argyll Jacket (no waistcoat +£75) on Scotweb here which is only 13oz but costs £250 and only for the jacket.

So there's my problem, I don't know what the indicator of quality here is and the Scotweb one seems expensive by comparison for reasons I'm unsure off.

Looking at the above, I'm edging towards the heritageofscotland jacket, but, am i making a mistake or do you have any other advice?

And by the way, is there a reason why some are called Argyle and not Argyll? Surely its just Argyll?

Thanks
