I’d consider Spexcel for some race fitting clothes. The fabric feels premium, it’s light, breathable and very elastic, although of course you are trading off some durability at such a low price (because of the stitching and all that jazz). Already did 2 centuries on my Spexcel bibs and I’ve been loving them.
I order from their store on Aliexpress. For around €40 you get both bib shorts and jersey.
