It may sound a little grimy, but I was able to stretch out the discount at jcrew recently and combine the 30% with the 15% student discount. They are not supposed to do it, but if you find a less informed worker you can push for it. Using a personal shopper, or the chat feature can also help
Mind you that you can get the 30% just by applying for the J.Crew card, and if you get turned down you can repeat the process.
I picked up the Ludlow Italian worsted wool suit in charcoal, size 34/s, and 30/30 for the pants. (came out to be about 380, with free overnight shipping)
as far as fit. The 34/s runs a little larger then suitsupply's 34, and fits like some more modern cuts of 36's
Fits very well off the rack, with just sleeves needing some work (slight trim, and shortened)
From what I can tell about the quality, it is comparable with similar priced Hugo Boss suits, and possibly a little better then the similar C.M suits.
I have strange measurements so unless I m going with an MTM or etc, finding a suit in my size that can be bought in separates saves me a lot of money.
Just for general knowledge, their XS jackets are for the most part a little longer then their 36s (which is already longer then most modern 36s)
