I don't have a problem with the complaints about the buldiings etc, on past form they're probably an understatement.
With the uniforms, I'd like to know which uniforms they have objections to.
No1's are meant to be fitted and smart so, if they aren't, then that is likely a combination of design and tailoring standards at kitting but, as we all know, the period of initial training tends to do all sorts of things to your body shape so anything tailored at the start of that probably won't fit at the end.
No 2s should fit as well but don't get the same levels of tailoring so design standards may be the issue and, let's be honest, nobody i know has tailored workwear - we all pick stuff 'off the peg' at Matalan, Tesco's or wherever we can get cheap shirts and trousers so why expect No2 s to be of any different standards?
As for combats, be they MTP or DPM, they have never looked smart on anyone - but they are intended to be practical rough workwear not parade wear so the focus on them should be do they achieve that object with comfort for the wearer, what they look like is a secondary consideration.
