Wear true to size if you want a straight slim cut. If you have regular/big thighs then you cannot size down, but if they are skinny you can try it. I have regular thighs and I sized down (31) from my regular size of 32. They stretched out fine everywhere but are a little tight in the thighs imo which makes them a little uncomfortable by the end of the day. Most of the fit pics I've seen that I like the most show ppl wearing them in true to size. Sizing up too much makes them look sloppy, and sizing down too much makes them look like girls jeans.
