What are the best suits for grooms on a budget?

I visited a menswear store to buy a groom suit for a wedding event two days ago. I wanted something simple and well fitted. I also wanted something that looks formal but stays within budget. But when I checked the suits I felt disappointed. Some suits looked cheap in fabric. Some were too expensive for basic design. Some did not fit properly. I could not trust them. I could not decide confidently.

Then I visited another shop in the same area. Some suits looked better but prices were still high. Some were affordable but stitching was not clean. Some looked perfect at first but fitting was not proper. I remembered a suit someone wore before that looked good but lost shape later. That made me hesitate even more.

To check more variety and options while scrolling many online marketplaces including alibaba I found many groom suits. Some looked modern and budget friendly. Some had better cuts and styles. Some showed good finishing in pictures. There were many options to compare. This made me excited but also confused again.

Now I am thinking should I trust online suits for better price or choose local stores for proper fitting? What would you do in my place?
