Note the pocket details before buying the suit.

If the seams pucker, don't buy the suit.

Make sure the buttons on the sleeve are neat, and have no loose threads hanging.

Inspect the general details and stitching, before buying the suit.

There are several things you should inspect when you buy a woman’s business suit. Just because the price tag is high, it may not be the best business attire for you. It goes with out saying that the suit should of course be fully lined. And super cheap quality lining will sooner or later rip, so stay away from that. Check the wrinkle factor of the suit material by grabbing  a part of the suit with one hand and crunch it all up with your fist – when you let go and the fabric falls out of your hand, you will see how wrinkle prone the material is. (Wool blends don’t wrinkle much; linen wrinkles a lot.) Inspect the seams at the lapels and the pockets – if anything looks less then perfect, don’t buy it. If you see a loose thread, pull it and see what happens. If there are too many loose threads, don’t buy it. Check the suit’s seams for any puckers (especially around the shoulder). If there are any puckers at all, ask the sales associate to steam them out – but if the puckers can’t be steamed out easily, it means the stitching was not done right to begin with when it was sewn, so don’t buy it. Inspect the buttons at the bottom of the sleeve to make sure they are neat and straight. Last, when you wear the business suit, look and see that the lining doesn’t poke out lower than the hem line at the edge of the  sleeves or at the bottom of the suit jacket.
