I stand tall at 5' 2" (130lbs) and I consider myself to be a fashion/clothes whore. With my height challenges, as you all know, it can be difficult to find RTW clothing.
Below is my current list of favorites that are easy to find, nice quality and require limited alterations:
The quality of the fabrics have suffered over the years, but the fits have improved.
Tailor Slim Trouser (28/28, 28/30) & Tailor Slim Shirts (XS, S)
The suits and blazers are too long, even with a 34S, but the pants are perfect and an upgrade from BR's fabrics.
Ludlow Slim & Classic Trousers (28/32)
With several lines of suiting, only 3 will allow jacket shortening without throwing off the proportion. The Havana has patch pockets which can easily be cropped and moved up. The Soho has jetted pockets and wide lapels. Stay away from the Madison as the lapels are larger than the Soho and you'll end up looking like Dumbo. 2cm is the most I recommend for jacket shortening.
Havana & Soho (size 32)
Shoes (size 5 UK)
Make sure to look for the suits that are made in Italy, as the ones made in the USA seem to fit one size larger.
Milano Suits (36S)
Brooks Brothers Black Fleece
Jacket and blazer cuts are shorter, so for a short guy, these fit perfectly. Prices are high, but wait for the sales.
Suits (BB00 equivalent to size 34)
Trousers (BB0 equivalent to size 28/30)
They carry a large selection of shoes in a size 6 and if there is a shoe you want and it's not available in your size, you can have them made to order. If you call and tell them you're a Style Forum member, they will not charge you the $125 fee! If you are a size 6 D/E, I have several pairs of AE shoes for sale. PM me.
I hope this helps!
