Tom Ford's suits are the best, bar none.
They're worth every penny if you can stomach the price tag.
The cut and fit are a notch above every other men's luxury boutique.
The store itself is really beautiful. The staff is extremely friendly and helpful, I'd definitely recommend going to Gini Kim. She is extremely knowledgeable about all of the products and is very accommodating.
If you do end up buying a piece, I'd also recommend that Yoko does the tailoring. She's incredibly thorough and does an amazing job.
