Champagne Taste on a Beer Budget: A Black Tie Guide
This portion of our Black Tie Guide dabbles in some luxurious indulgences that some would consider optional. You might not necessarily need them immediately, but consider them things to upgrade as you build your tuxedo ensemble.
Part 5: Hosiery, Sock Garters & Braces
Black tie might be the only time wearing black socks can be considered acceptable. Formal hose should be over-the-calf, as mid-calf socks tend to slouch and expose your bare skin, which looks bad. 
In terms of material, the preference is for silk, which has a sense of refinement and sheen that compliments the silk piping of the trouser and shine of the shoes. 
Socks made of 100% silk do have trouble staying up on their own and can require the use of sock garters. If you’d rather dispense with having to wear those, then you’ll probably opt for the also-cheaper silk socks blended with nylon, which are more common to find.
The cheapest silk socks I’ve found come from Brooks Brothers, for around $40. You can also get pairs from Kabbaz-Kelly & Sons made by Marcoliani and Bresciani, who also have pure 100% silk hose. A Suitable Wardrobe’s Store also has pure silk hose for $55. 
If you need sock garters, then you can either search eBay U.K. or go with Brooks Brothers or Cable Car Clothiers, which has them for $38 and $45, respectively.
In regards to braces (commonly called “suspenders”), these are a great way to keep your trousers up and any pair of pants can have buttons added to the waistband to attach the braces. Remember: proper braces fasten using buttons, not alligator-clips.
Braces should be kept simple and discrete, avoiding the temptation of being flashy with bright colors or patterns (you shouldn’t be removing your jacket anyway). Go for solid black or white. I prefer white as it blends together better with the white shirt, but some might like the contrast of black. 
Braces should also be sized properly so the metal adjusters are on the bottom toward the waist, not high on the chest. 
As for where to buy, braces made by Albert Thurston come highly regarded and they actually seem to be very competitively priced at $75 at A Suitable Wardrobe’s Store in ivory barathea and both black and white moiré. 
The one thing I want to point out about the items mentioned in this part is that they’re probably not necessary for the most basic of tuxedo ensembles. If you pants are sized correctly to your waist, you can forgo braces. Cheaper socks can be found by going with cotton or wool options from the same high-end makers. For instance, Howard Yount carries several black over-the-calf options from their own private-label and from Marcoliani.
