I have the Assos half-short, the Uma jacket, the roubaix bib knicker & the bib tight. I completely disagree with "order a size up". I am a consistent size small across most European lines, and size small in Assos fits me perfectly. I ordered up a size in the half-short by going with medium, and it was a big mistake. It is baggy in the butt, and the leg openings are too big. The cut of their garments is very snug, because that is how it is designed to fit. A lot of people won't like that, so they won't buy Assos. But now that I have gotten used to it, I can't stand the looser fit of some of the American lines I had purchased previously. I don't like bike clothes to flap as I'm riding.

The arms & legs on the winter garments are cut narrow, and the wind-blocking fabrics are stiff, so it can be a challenge to pull the pieces on over base layers. But once they're on, they are great. Anyway, you're not looking at the winter garments. You're interested in lycra shorts. So you don't need to worry about too tight in the sleeves or legs.

For sizing, I have found the size charts posted on the web-sites to be inconsistent. So please, please, please, go to a store to try on before you buy. I am 5'2", weigh 107 lbs, have a 26 inch waist & 35 inch hips. Some of the size charts would put me in a medium, some in a small. I wear small.
