What I Look for in Fabric Quality
My first priority is always the fabric. I check whether the silk feels smooth, breathable, and well-made.

Style Details I Pay Attention To
Even though they are a base layer, I still care about style. I look at the rise of the waistband, the length of the legs, and whether the cuffs sit well under other clothing. I also like neutral colors because they are easier to wear under different outfits.
My Thoughts on Price and Value
