Fast and easy to order and a good quality item too. Personally I should have ordered the 17" collar slim fit as my measured size of 16.5" is a touch tight.
Strengths
Ease of ordering, maintaining my measurements for easy repeat orders, clarity of price for "add-ins" eg; collar/cuff linings.
Improvements or suggestions
At £29 for an introductory offer this is a good price and I would return again at this price bracket. I'd find it difficult to maintain repeat orders at the regular price (£49)
