Aritzia's $128 Wool-Cashmere Knit Sweater against Reformation's $178 Cashmere Crew, a $50 gap in the mid-gauge knitwear tier. The catch on the Aritzia side is that its fiber varies by style — merino, wool-cashmere, or a plush synthetic blend — while Reformation is consistently recycled cashmere, wool, or cotton with quality rated high for its tier.

The case for Aritzia
At $128 the Aritzia sweater in its merino or wool-cashmere versions is genuinely fair value with a soft hand and on-trend oversized or cropped cuts, undercutting Reformation by $50 — just avoid the polyester-blend plush styles, which pill and are the weakest buy here.
The case for Reformation
The Reformation crew is the higher-quality knit for its tier, in recycled cashmere with a clean contemporary true-to-size fit, for shoppers who want real cashmere with an eco story rather than a trend cut.

VerdictWhat the extra money buys

If you can find an Aritzia style in merino or wool-cashmere, buy it — you get real animal fiber and the current cut for $50 less, and that closes most of the quality gap. Step up to Reformation if you want cashmere specifically and a clean fit that outlasts a trend cycle, but know its recycled cashmere pills early as fine cashmere does, so budget for a comb either way. Do not pay $128 for Aritzia's plush synthetic styles; that is the one clear loser in this matchup. Check the fiber content before checking out.
