Then I’ve got a few pointers as to where you can get a look like the vid.
This one is one of my all-time video favourites, with the lads repping a classic mod look, suits, ties, the works. With the striped tie, it's a bit more college / Ivy League than usual.

Price: £220
I suspect the video is more of a navy suit vibe, but Adaptor do some very good and inexpensive off-the-peg whistles. This electric blue suit is a blue they’ve still got in stock, but they've got a few others, mostly patterned fabrics.

Price: £55
Pretty straightforward, so might as well go with somewhere reliable. Adam’s is a great little shop and they can be relied upon to get the look right when it comes to collar rolls, etc.

Price: £7.99
Ties planet are good for cheap, skinny ties. They’re not silk, but the quality is decent. I actually think this might be a bit bright for the original video, but it’ll go with the electric blue suit.
Couldn’t get a decent look at the shoes in this vid, so can’t make any recommendations, but it’ll probably push the price up if you’re looking to complete the look. Other than that, this one is a pretty strong, smart mod outfit for less than £300.
